/////////////////////
// InSim for Live for Speed : 0.6B
// InSim allows communication between up to 8 external programs and LFS.
// TCP or UDP packets can be sent in both directions, LFS reporting various
// things about its state, and the external program requesting info and
// controlling LFS with special packets, text commands or keypresses.
// NOTE : This text file was written with a TAB size equal to 4 spaces.
// INSIM VERSION NUMBER (updated for version 0.6B)
// ====================
const int INSIM_VERSION = 5;
// CHANGES
// =======
// Version 0.5Z (no change to INSIM_VERSION)
// NLP / MCI packets are now output at regular intervals
// CCI_LAG bit added to the CompCar structure
// Version 0.6B (INSIM_VERSION increased to 5)
// Lap timing info added to IS_RST (Timing byte)
// NLP / MCI minimum time interval reduced to 40 ms (was 50 ms)
// IS_VTC now cancels game votes even if the majority has not been reached
// IS_MTC (Msg To Connection) now has a variable length (up to 128 characters)
// IS_MTC can be sent to all (UCID = 255) and sound effect can be specified
// IS_CON reports contact between two cars (if ISF_CON is set)
// IS_OBH reports information about any object hit (if ISF_OBH is set)
// IS_HLV reports incidents that would violate HLVC (if ISF_HLV is set)
// IS_PLC sets allowed cars for individual players
// IS_AXM to add / remove / clear autocross objects
// IS_ACR reports successful or attempted admin commands
// OG_SHIFT and OG_CTRL (keys) bits added to OutGaugePack
// New IS_RIP option RIPOPT_FULL_PHYS to use full physics when searching
// ISS_SHIFTU_HIGH is no longer used (no high / low view distinction)
// FIX : Clutch axis / button was not reported from Controls screen
// FIX : TTime in IS_RIP was wrong in mid-joined Multiplayer Replays
// FIX : IS_BTN did not allow the documented limit of 240 characters
// FIX : OutGaugePack ID was always zero regardless of ID in cfg.txt
// FIX : InSim camera with vertical pitch would cause LFS to crash
// TYPES : (all multi-byte types are PC style - lowest byte first)
// =====
// char 1-byte character
// byte 1-byte unsigned integer
// word 2-byte unsigned integer
// short 2-byte signed integer
// unsigned 4-byte unsigned integer
// int 4-byte signed integer
// float 4-byte float
// RaceLaps (rl) : (various meanings depending on range)
// 0 : practice
// 1-99 : number of laps... laps = rl
// 100-190 : 100 to 1000 laps... laps = (rl - 100) * 10 + 100
// 191-238 : 1 to 48 hours... hours = rl - 190
// InSim PACKETS
// =============
// All InSim packets use a four byte header
// Size : total packet size - a multiple of 4
// Type : packet identifier from the ISP_ enum (see below)
// ReqI : non zero if the packet is a packet request or a reply to a request
// Data : the first data byte
// INITIALISING InSim
// ==================
// To initialise the InSim system, type into LFS : /insim xxxxx
// where xxxxx is the TCP and UDP port you want LFS to open.
// OR start LFS with the command line option : LFS /insim=xxxxx
// This will make LFS listen for packets on that TCP and UDP port.
// TO START COMMUNICATION
// ======================
// TCP : Connect to LFS using a TCP connection, then send this packet :
// UDP : No connection required, just send this packet to LFS :
struct IS_ISI // InSim Init - packet to initialise the InSim system
{
byte Size; // 44
byte Type; // ISP_ISI
byte ReqI; // If non-zero LFS will send an IS_VER packet
byte Zero; // 0
word UDPPort; // Port for UDP replies from LFS (0 to 65535)
word Flags; // Bit flags for options (see below)
byte Sp0; // 0
byte Prefix; // Special host message prefix character
word Interval; // Time in ms between NLP or MCI (0 = none)
char Admin[16]; // Admin password (if set in LFS)
char IName[16]; // A short name for your program
};
// NOTE 1) UDPPort field when you connect using UDP :
// zero : LFS sends all packets to the port of the incoming packet
// non-zero : LFS sends all packets to the specified UDPPort
// NOTE 2) UDPPort field when you connect using TCP :
// zero : LFS sends NLP / MCI packets using your TCP connection
// non-zero : LFS sends NLP / MCI packets to the specified UDPPort
// NOTE 3) Flags field (set the relevant bits to turn on the option) :
#define ISF_RES_0 1 // bit 0 : spare
#define ISF_RES_1 2 // bit 1 : spare
#define ISF_LOCAL 4 // bit 2 : guest or single player
#define ISF_MSO_COLS 8 // bit 3 : keep colours in MSO text
#define ISF_NLP 16 // bit 4 : receive NLP packets
#define ISF_MCI 32 // bit 5 : receive MCI packets
#define ISF_CON 64 // bit 6 : receive CON packets
#define ISF_OBH 128 // bit 7 : receive OBH packets
#define ISF_HLV 256 // bit 8 : receive HLV packets
#define ISF_AXM_LOAD 512 // bit 9 : receive AXM when loading a layout
#define ISF_AXM_EDIT 1024 // bit 10 : receive AXM when changing objects
// In most cases you should not set both ISF_NLP and ISF_MCI flags
// because all IS_NLP information is included in the IS_MCI packet.
// The ISF_LOCAL flag is important if your program creates buttons.
// It should be set if your program is not a host control system.
// If set, then buttons are created in the local button area, so
// avoiding conflict with the host buttons and allowing the user
// to switch them with SHIFT+B rather than SHIFT+I.
// NOTE 4) Prefix field, if set when initialising InSim on a host :
// Messages typed with this prefix will be sent to your InSim program
// on the host (in IS_MSO) and not displayed on anyone's screen.

};
// GENERAL PURPOSE PACKETS - IS_TINY (4 bytes) and IS_SMALL (8 bytes)
// =======================
// To avoid defining several packet structures that are exactly the same, and to avoid
// wasting the ISP_ enumeration, IS_TINY is used at various times when no additional data
// other than SubT is required. IS_SMALL is used when an additional integer is needed.
// IS_TINY - used for various requests, replies and reports
struct IS_TINY // General purpose 4 byte packet
{
byte Size; // always 4
byte Type; // always ISP_TINY
byte ReqI; // 0 unless it is an info request or a reply to an info request
byte SubT; // subtype, from TINY_ enumeration (e.g. TINY_RACE_END)
};
// IS_SMALL - used for various requests, replies and reports
struct IS_SMALL // General purpose 8 byte packet
{
byte Size; // always 8
byte Type; // always ISP_SMALL
byte ReqI; // 0 unless it is an info request or a reply to an info request
byte SubT; // subtype, from SMALL_ enumeration (e.g. SMALL_SSP)
unsigned UVal; // value (e.g. for SMALL_SSP this would be the OutSim packet rate)
};
// VERSION REQUEST
// ===============
// It is advisable to request version information as soon as you have connected, to
// avoid problems when connecting to a host with a later or earlier version. You will
// be sent a version packet on connection if you set ReqI in the IS_ISI packet.
// This version packet can be sent on request :
struct IS_VER // VERsion
{
byte Size; // 20
byte Type; // ISP_VERSION
byte ReqI; // ReqI as received in the request packet
byte Zero;
char Version[8]; // LFS version, e.g. 0.3G
char Product[6]; // Product : DEMO or S1
word InSimVer; // InSim Version : increased when InSim packets change
};
// To request an InSimVersion packet at any time, send this IS_TINY :
// ReqI : non-zero (returned in the reply)
// SubT : TINY_VER (request an IS_VER)
// CLOSING InSim
// =============
// You can send this IS_TINY to close the InSim connection to your program :
// ReqI : 0
// SubT : TINY_CLOSE (close this connection)
// Another InSimInit packet is then required to start operating again.
// You can shut down InSim completely and stop it listening at all by typing /insim=0
// into LFS (or send a MsgTypePack to do the same thing).
// MAINTAINING THE CONNECTION - IMPORTANT
// ==========================
// If InSim does not receive a packet for 70 seconds, it will close your connection.
// To open it again you would need to send another InSimInit packet.
// LFS will send a blank IS_TINY packet like this every 30 seconds :
// ReqI : 0
// SubT : TINY_NONE (keep alive packet)
// You should reply with a blank IS_TINY packet :
// ReqI : 0
// SubT : TINY_NONE (has no effect other than resetting the timeout)
// NOTE : If you want to request a reply from LFS to check the connection
// at any time, you can send this IS_TINY :
// ReqI : non-zero (returned in the reply)
// SubT : TINY_PING (request a TINY_REPLY)
// LFS will reply with this IS_TINY :
// ReqI : non-zero (as received in the request packet)
// SubT : TINY_REPLY (reply to ping)
// STATE REPORTING AND REQUESTS
// ============================
// LFS will send a StatePack any time the info in the StatePack changes.
struct IS_STA // STAte
{
byte Size; // 28
byte Type; // ISP_STA
byte ReqI; // ReqI if replying to a request packet
byte Zero;

byte ReqI; // 0
byte Zero;
int Bits16; // set to choose 16-bit
int RR; // refresh rate - zero for default
int Width; // 0 means go to window
int Height; // 0 means go to window
};
// The refresh rate actually selected by LFS will be the highest available rate
// that is less than or equal to the specified refresh rate. Refresh rate can
// be specified as zero in which case the default refresh rate will be used.
// If Width and Height are both zero, LFS will switch to windowed mode.
// TEXT MESSAGES AND KEY PRESSES
// ==============================
// You can send 64-byte text messages to LFS as if the user had typed them in.
// Messages that appear on LFS screen (up to 128 bytes) are reported to the
// external program. You can also send simulated keypresses to LFS.

// SubT : TINY_ISM (request an IS_ISM)
// NOTE : If LFS is not in multiplayer mode, the host name in the ISM will be empty.
// VOTE NOTIFY AND CANCEL
// ======================
// LFS notifies the external program of any votes to restart or qualify

// ============
// You can send a packet to limit the cars that can be used by a given connection

// RACE TRACKING
// =============
// In LFS there is a list of connections AND a list of players in the race
// Some packets are related to connections, some players, some both
// If you are making a multiplayer InSim program, you must maintain two lists
// You should use the unique identifier UCID to identify a connection
// Each player has a unique identifier PLID from the moment he joins the race, until he
// leaves. It's not possible for PLID and UCID to be the same thing, for two reasons :
// 1) there may be more than one player per connection if AI drivers are used
// 2) a player can swap between connections, in the case of a driver swap (IS_TOC)
// When all players are cleared from race (e.g. /clear) LFS sends this IS_TINY
// ReqI : 0
// SubT : TINY_CLR (CLear Race)
// When a race ends (return to game setup screen) LFS sends this IS_TINY

// If PMOFlags bit 0 is set in a PMO_LOADING_FILE packet, LFS has reached the end of
// a layout file which it is loading. The added objects will then be optimised.
// Optimised in this case means that static vertex buffers will be created for all
// objects, to greatly improve the frame rate. The problem with this is that when
// there are many objects loaded, optimisation causes a significant glitch which can
// be long enough to cause a driver who is cornering to lose control and crash.
// PMOFlags bit 0 can also be set in an IS_AXM with PMOAction of PMO_ADD_OBJECTS.
// This causes all objects to be optimised. It is important not to set bit 0 in
// every packet you send to add objects or you will cause severe glitches on the
// clients computers. It is ok to have some objects on the track which are not
// optimised. So if you have a few objects that are being removed and added
// occasionally, the best advice is not to request optimisation at all. Only
// request optimisation (by setting bit 0) if you have added so many objects
// that it is needed to improve the frame rate.
// NOTE 1) LFS makes sure that all objects are optimised when the race restarts.
// NOTE 2) In the 'more' section of SHIFT+U there is info about optimised objects.
// If you are using InSim to send many packets of objects (for example loading an
// entire layout through InSim) then you must take care of the bandwidth and buffer
// overflows. You must not try to send all the objects at once. It's probably good
// to use LFS's method of doing this : send the first packet of objects then wait for
// the corresponding IS_AXM that will be output when the packet is processed. Then
// you can send the second packet and again wait for the IS_AXM and so on.

// ReqI : 0
// SubT : SMALL_SSP (Start Sending Positions)
// UVal : interval (time between updates - zero means stop sending)
// If OutSim has not been setup in cfg.txt, the SSP packet makes LFS send UDP packets
// if in game, using the OutSim system as documented near the end of this text file.
// You do not need to set any OutSim values in LFS cfg.txt - OutSim is fully
// initialised by the SSP packet.
// The OutSim packets will be sent to the UDP port specified in the InSimInit packet.
// NOTE : OutSim packets are not InSim packets and don't have a 4-byte header.
// DASHBOARD PACKETS (Initialising OutGauge from InSim - See "OutGauge" below)
// =================
// To request Dashboard Packets from the currently viewed car, send this IS_SMALL :
// ReqI : 0
// SubT : SMALL_SSG (Start Sending Gauges)
// UVal : interval (time between updates - zero means stop sending)
// If OutGauge has not been setup in cfg.txt, the SSG packet makes LFS send UDP packets
// if in game, using the OutGauge system as documented near the end of this text file.
// You do not need to set any OutGauge values in LFS cfg.txt - OutGauge is fully
// initialised by the SSG packet.
// The OutGauge packets will be sent to the UDP port specified in the InSimInit packet.
// NOTE : OutGauge packets are not InSim packets and don't have a 4-byte header.
// CAMERA CONTROL
// ==============
// IN GAME camera control
// ----------------------
// You can set the viewed car and selected camera directly with a special packet
// These are the states normally set in game by using the TAB and V keys
struct IS_SCC // Set Car Camera - Simplified camera packet (not SHIFT+U mode)
{
byte Size; // 8
byte Type; // ISP_SCC
byte ReqI; // 0
byte Zero;
byte ViewPLID; // Unique ID of player to view
byte InGameCam; // InGameCam (as reported in StatePack)
byte Sp2;
byte Sp3;
};
// NOTE : Set InGameCam or ViewPLID to 255 to leave that option unchanged.
// DIRECT camera control
// ---------------------
// A Camera Position Packet can be used for LFS to report a camera position and state.
// An InSim program can also send one to set LFS camera position in game or SHIFT+U mode.
// Type : "Vec" : 3 ints (X, Y, Z) - 65536 means 1 metre
struct IS_CPP // Cam Pos Pack - Full camera packet (in car OR SHIFT+U mode)
{
byte Size; // 32
byte Type; // ISP_CPP
byte ReqI; // instruction : 0 / or reply : ReqI as received in the TINY_SCP
byte Zero;
Vec Pos; // Position vector
word H; // heading - 0 points along Y axis
word P; // pitch - 0 means looking at horizon
word R; // roll - 0 means no roll
byte ViewPLID; // Unique ID of viewed player (0 = none)
byte InGameCam; // InGameCam (as reported in StatePack)
float FOV; // 4-byte float : FOV in degrees
word Time; // Time in ms to get there (0 means instant)
word Flags; // ISS state flags (see below)
};
// The ISS state flags that can be set are :
// ISS_SHIFTU - in SHIFT+U mode
// ISS_SHIFTU_FOLLOW - FOLLOW view
// ISS_VIEW_OVERRIDE - override user view
// On receiving this packet, LFS will set up the camera to match the values in the packet,
// including switching into or out of SHIFT+U mode depending on the ISS_SHIFTU flag.
// If ISS_VIEW_OVERRIDE is set, the in-car view Heading Pitch and Roll (but not FOV) will
// be taken from the values in this packet. Otherwise normal in game control will be used.
// Position vector (Vec Pos) - in SHIFT+U mode, Pos can be either relative or absolute.
// If ISS_SHIFTU_FOLLOW is set, it's a following camera, so the position is relative to
// the selected car. Otherwise, the position is absolute, as used in normal SHIFT+U mode.
// NOTE : Set InGameCam or ViewPLID to 255 to leave that option unchanged.
// SMOOTH CAMERA POSITIONING
// --------------------------
// The "Time" value in the packet is used for camera smoothing. A zero Time means instant
// positioning. Any other value (milliseconds) will cause the camera to move smoothly to
// the requested position in that time. This is most useful in SHIFT+U camera modes or
// for smooth changes of internal view when using the ISS_VIEW_OVERRIDE flag.
// NOTE : You can use frequently updated camera positions with a longer Time value than
// the update frequency. For example, sending a camera position every 100 ms, with a
// Time value of 1000 ms. LFS will make a smooth motion from the rough inputs.
// If the requested camera mode is different from the one LFS is already in, it cannot
// move smoothly to the new position, so in this case the "Time" value is ignored.
// GETTING A CAMERA PACKET
// -----------------------
// To GET a CamPosPack from LFS, send this IS_TINY :
// ReqI : non-zero (returned in the reply)
// SubT : TINY_SCP (Send Cam Pos)
// LFS will reply with a CamPosPack as described above. You can store this packet
// and later send back exactly the same packet to LFS and it will try to replicate
// that camera position.
// TIME CONTROL
// ============
// Request the current time at any point with this IS_TINY :
// ReqI : non-zero (returned in the reply)
// SubT : TINY_GTH (Get Time in Hundredths)
// The time will be sent back in this IS_SMALL :
// ReqI : non-zero (as received in the request packet)
// SubT : SMALL_RTP (Race Time Packet)
// UVal : Time (hundredths of a second since start of race or replay)
// You can stop or start time in LFS and while it is stopped you can send packets to move
// time in steps. Time steps are specified in hundredths of a second.
// Warning : unlike pausing, this is a "trick" to LFS and the program is unaware of time
// passing so you must not leave it stopped because LFS is unusable in that state.
// This packet is not available in live multiplayer mode.
// Stop and Start with this IS_SMALL :
// ReqI : 0
// SubT : SMALL_TMS (TiMe Stop)
// UVal : stop (1 - stop / 0 - carry on)
// When STOPPED, make time step updates with this IS_SMALL :
// ReqI : 0
// SubT : SMALL_STP (STeP)
// UVal : number (number of hundredths of a second to update)
// REPLAY CONTROL
// ==============
// You can load a replay or set the position in a replay with an IS_RIP packet.
// Replay positions and lengths are specified in hundredths of a second.
// LFS will reply with another IS_RIP packet when the request is completed.
struct IS_RIP // Replay Information Packet
{
byte Size; // 80
byte Type; // ISP_RIP
byte ReqI; // request : non-zero / reply : same value returned
byte Error; // 0 or 1 = OK / other values are listed below
byte MPR; // 0 = SPR / 1 = MPR
byte Paused; // request : pause on arrival / reply : paused state

unsigned CTime; // (hundredths) request : destination / reply : position
unsigned TTime; // (hundredths) request : zero / reply : replay length
char RName[64]; // zero or replay name - last byte must be zero
};
// NOTE about RName :
// In a request, replay RName will be loaded. If zero then the current replay is used.
// In a reply, RName is the name of the current replay, or zero if no replay is loaded.
// You can request an IS_RIP packet at any time with this IS_TINY :
// ReqI : non-zero (returned in the reply)
// SubT : TINY_RIP (Replay Information Packet)
// Error codes returned in IS_RIP replies :
enum
{
RIP_OK, // 0 - OK : completed instruction
RIP_ALREADY, // 1 - OK : already at the destination
RIP_DEDICATED, // 2 - can't run a replay - dedicated host
RIP_WRONG_MODE, // 3 - can't start a replay - not in a suitable mode
RIP_NOT_REPLAY, // 4 - RName is zero but no replay is currently loaded
RIP_CORRUPTED, // 5 - IS_RIP corrupted (e.g. RName does not end with zero)
RIP_NOT_FOUND, // 6 - the replay file was not found
RIP_UNLOADABLE, // 7 - obsolete / future / corrupted
RIP_DEST_OOB, // 8 - destination is beyond replay length
RIP_UNKNOWN, // 9 - unknown error found starting replay
RIP_USER, // 10 - replay search was terminated by user
RIP_OOS, // 11 - can't reach destination - SPR is out of sync
};
// Options byte : some options
#define RIPOPT_LOOP 1 // replay will loop if this bit is set
#define RIPOPT_SKINS 2 // set this bit to download missing skins
#define RIPOPT_FULL_PHYS 4 // use full physics when searching an MPR
// NOTE : RIPOPT_FULL_PHYS makes MPR searching much slower so should not normally be used.
// This flag was added to allow high accuracy MCI packets to be output when fast forwarding.
// SCREENSHOTS
// ===========
// You can instuct LFS to save a screenshot using the IS_SSH packet.
// The screenshot will be saved as an uncompressed BMP in the data\shots folder.
// BMP can be a filename (excluding .bmp) or zero - LFS will create a file name.
// LFS will reply with another IS_SSH when the request is completed.
struct IS_SSH // ScreenSHot
{
byte Size; // 40
byte Type; // ISP_SSH
byte ReqI; // request : non-zero / reply : same value returned

SSH_NO_SAVE, // 3 - could not save the screenshot
};
// BUTTONS
// =======
// You can make up to 240 buttons appear on the host or guests (ID = 0 to 239).
// You should set the ISF_LOCAL flag (in IS_ISI) if your program is not a host control
// system, to make sure your buttons do not conflict with any buttons sent by the host.
// LFS can display normal buttons in these four screens :
// - main entry screen
// - game setup screen
// - in game
// - SHIFT+U mode
// The recommended area for most buttons is defined by :
#define IS_X_MIN 0
#define IS_X_MAX 110
#define IS_Y_MIN 30
#define IS_Y_MAX 170
// If you draw buttons in this area, the area will be kept clear to
// avoid overlapping LFS buttons with your InSim program's buttons.
// Buttons outside that area will not have a space kept clear.
// You can also make buttons visible in all screens - see below.
// To delete one button or clear all buttons, send this packet :
struct IS_BFN // Button FunctioN - delete buttons / receive button requests
{
byte Size; // 8
byte Type; // ISP_BFN
byte ReqI; // 0
byte SubT; // subtype, from BFN_ enumeration (see below)
byte UCID; // connection to send to or from (0 = local / 255 = all)
byte ClickID; // ID of button to delete (if SubT is BFN_DEL_BTN)
byte Inst; // used internally by InSim
byte Sp3;
};
enum // the fourth byte of IS_BFN packets is one of these
{
BFN_DEL_BTN, // 0 - instruction : delete one button (must set ClickID)
BFN_CLEAR, // 1 - instruction : clear all buttons made by this insim instance
BFN_USER_CLEAR, // 2 - info : user cleared this insim instance's buttons
BFN_REQUEST, // 3 - user request : SHIFT+B or SHIFT+I - request for buttons
};
// NOTE : BFN_REQUEST allows the user to bring up buttons with SHIFT+B or SHIFT+I
// SHIFT+I clears all host buttons if any - or sends a BFN_REQUEST to host instances
// SHIFT+B is the same but for local buttons and local instances
// To send a button to LFS, send this variable sized packet
struct IS_BTN // BuTtoN - button header - followed by 0 to 240 characters
{
byte Size; // 12 + TEXT_SIZE (a multiple of 4)
byte Type; // ISP_BTN
byte ReqI; // non-zero (returned in IS_BTC and IS_BTT packets)
byte UCID; // connection to display the button (0 = local / 255 = all)
byte ClickID; // button ID (0 to 239)
byte Inst; // some extra flags - see below
byte BStyle; // button style flags - see below
byte TypeIn; // max chars to type in - see below
byte L; // left : 0 - 200
byte T; // top : 0 - 200
byte W; // width : 0 - 200
byte H; // height : 0 - 200
// char Text[TEXT_SIZE]; // 0 to 240 characters of text
};
// ClickID byte : this value is returned in IS_BTC and IS_BTT packets.
// Host buttons and local buttons are stored separately, so there is no chance of a conflict between
// a host control system and a local system (although the buttons could overlap on screen).
// Programmers of local InSim programs may wish to consider using a configurable button range and
// possibly screen position, in case their users will use more than one local InSim program at once.
// TypeIn byte : if set, the user can click this button to type in text.
// Lowest 7 bits are the maximum number of characters to type in (0 to 95)
// Highest bit (128) can be set to initialise dialog with the button's text
// On clicking the button, a text entry dialog will be opened, allowing the specified number of
// characters to be typed in. The caption on the text entry dialog is optionally customisable using
// Text in the IS_BTN packet. If the first character of IS_BTN's Text field is zero, LFS will read
// the caption up to the second zero. The visible button text then follows that second zero.
// Text : 65-66-67-0 would display button text "ABC" and no caption
// Text : 0-65-66-67-0-68-69-70-71-0-0-0 would display button text "DEFG" and caption "ABC"
// Inst byte : mainly used internally by InSim but also provides some extra user flags
#define INST_ALWAYS_ON 128 // if this bit is set the button is visible in all screens
// NOTE : You should not use INST_ALWAYS_ON for most buttons. This is a special flag for buttons
// that really must be on in all screens (including the garage and options screens). You will
// probably need to confine these buttons to the top or bottom edge of the screen, to avoid
// overwriting LFS buttons. Most buttons should be defined without this flag, and positioned
// in the recommended area so LFS can keep a space clear in the main screens.
// BStyle byte : style flags for the button
#define ISB_C1 1 // you can choose a standard
#define ISB_C2 2 // interface colour using
#define ISB_C4 4 // these 3 lowest bits - see below
#define ISB_CLICK 8 // click this button to send IS_BTC
#define ISB_LIGHT 16 // light button
#define ISB_DARK 32 // dark button
#define ISB_LEFT 64 // align text to left
#define ISB_RIGHT 128 // align text to right
// colour 0 : light grey (not user editable)
// colour 1 : title colour (default:yellow)
// colour 2 : unselected text (default:black)
// colour 3 : selected text (default:white)
// colour 4 : ok (default:green)
// colour 5 : cancel (default:red)
// colour 6 : text string (default:pale blue)
// colour 7 : unavailable (default:grey)
// NOTE : If width or height are zero, this would normally be an invalid button. But in that case if
// there is an existing button with the same ClickID, all the packet contents are ignored except the
// Text field. This can be useful for updating the text in a button without knowing its position.
// For example, you might reply to an IS_BTT using an IS_BTN with zero W and H to update the text.
// Replies : If the user clicks on a clickable button, this packet will be sent :
struct IS_BTC // BuTton Click - sent back when user clicks a button
{
byte Size; // 8
byte Type; // ISP_BTC
byte ReqI; // ReqI as received in the IS_BTN
byte UCID; // connection that clicked the button (zero if local)

byte Sp3;
};
// CFlags byte : click flags
#define ISB_LMB 1 // left click
#define ISB_RMB 2 // right click
#define ISB_CTRL 4 // ctrl + click
#define ISB_SHIFT 8 // shift + click
// If the TypeIn byte is set in IS_BTN the user can type text into the button
// In that case no IS_BTC is sent - an IS_BTT is sent when the user presses ENTER
struct IS_BTT // BuTton Type - sent back when user types into a text entry button
{
byte Size; // 104
byte Type; // ISP_BTT
