New page

== Introduction ==

The '''S'''ingle '''CH'''aracter 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 ==

=== 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.
