| IS_TTC | |
|---|---|
| General purpose 8-byte packet | |
| Overview | |
| Size | 8 |
| Type | ISP_TTC (5) |
| Usage | both ways |
| Previous packet IS_SMALL |
Next packet IS_STA |
The Target To Connection packet is sent to LFS to request information about a remote connection.
Packet details
| Type | Name | Description |
|---|---|---|
| byte | Size | 8 |
| byte | Type | ISP_TTC |
| byte | ReqI | 0 unless it is an info request or a reply to an info request |
| byte | SubT | subtype, from TTC_ enumeration (e.g. TTC_SEL) |
| byte | UCID | connection's unique id (0 = local) |
| byte | B1 | B1, B2, B3 may be used in various ways depending on SubT |
| byte | B2 | |
| byte | B3 |
Size
The packet size, always 8 bytes.
Type
The packet type from the ISP_ enumeration, always ISP_TTC.
ReqI
For an info request, this value must bet non-zero, and LFS will include the same ReqI in its reply. Otherwise, it should be zero.
SubT
The packet's subtype, which is a value from the TTC_ enumeration.
- TTC_NONE: Not used.
- TTC_SEL: Send to request an IS_AXM packet for the current layout editor selection.
- TTC_SEL_START: Send to request an IS_AXM packet very time the layout editor selection changes.
- TTC_SEL_STOP: Send to stop receiving [IS_AXM]] packets for every layout editor selection change.
UCID
The connection's unique ID. A value of 0 represents the local connection.
Values
B1, B2, and B3 can contain data depending on the value of SubT. At the time of writing (LFS 0.8B/InSim 10), no sub-type uses those values.
