Overview

Type	ISP_SCH (6)
Usage	instruction
Previous packet IS_STA	Next packet IS_SFP

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.
