[OZAPRS] alternative to KA9Q NOS ?

I think the extended AX25 that Linux supports addresses those issues. It 
can certainly handle Maxframe 127 instead of just 7.

I played with it over a wire link between a YAM 9k6 modem and the Baycom 
USCC>4 card 9k6 modem some years back. I remember being impressed by the 
performance compared with 1k2 packet.
