Aircraft config packets get forwarded

[norrisng]

Aircraft config packets ($CQ, @N, @S etc.) also get forwarded by the client.

Examples (as seen inside Discord):

AAL123:
Here's a test message
$CQLAN2250:@94836:ACC:{"config":{"lights":{"strobe_on":true}}

LON_CTR:
Insert message here
@ N:EZY123:2000:1:47.81881:9.46934:33358:439:4257229744:-172

It appears that these packets can appear before or after any message packet. Seems like multiple FSD packets are (randomly) bundled into a single TCP packet's payload.

Packets are separated via line breaks, and it appears that existing clients enforce this by not allowing line breaks to be entered in messages.

For instance, when text containing line breaks are pasted into vPilot, it will remove everything after the first line break.

In other words, it should be safe to assume that \r\n marks the end of an FSD packet in all cases.
