IS SCH
Introduction
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.
