The Single CHaracter packet is used to send individual key presses to LFS. Standard keys (e.g. V and H) should be sent as capital letters, using the corresponding ASCII values. This does not work with keys such as F-keys, arrows, Ctrl, etc. For those, you should send an IS_MST packet with the /press, /shift, /ctrl, or /alt commands.
Note that some keys seem not to work properly with this packet, for instance H does not toggle chat history, and I does not toggle ignition. On the other hand, V does change the view, and 9 does turn the hazard lights on.
Packet details
| Type | Name | Description |
|---|---|---|
| byte | Size | 8 |
| byte | Type | ISP_SCH |
| byte | ReqI | 0 |
| byte | Zero | |
| byte | CharB | key to press |
| byte | Flags | bit 0: SHIFT / bit 1: CTRL |
| byte | Spare2 | |
| byte | Spare3 |
Size
The size of the packet, always 8 bytes.
Type
The packet type from the ISP_ enumeration, always ISP_SCH.
ReqI
ReqI is always zero.
CharB
The byte representing the key to press. You can use non-printable characters, such as 13 to send an ↵ Enter key press.
Flags
2 bits are used to represent the ⇧ Shift (bit 0) and Ctrl (bit 1) keys being pressed. For instance, sending M with Flags 2 corresponds to pressing Ctrl + M.
