I believe that any time Xastir talks to a TNC via the serial port directly, 
it has a delay between characters so as not to foul up some slow TNCs. I 
just installed the linux ax.25 parts and use it that way. It transmits with 
less delay because Xastir just dumps the whole packet to the ax.25 system 
which then dumps the whole thing to the TNC, not really caring much about 
tripping up the slow TNCs.

I think. ;-)
