AX.25 started as X.25 but expanded the address field from 8 bits to 8 bytes. I believe a lot of work also was applied to various protocol timers to deal with very slow RF networks (300 and 1200 baud is common) and slow-to-key radios. Am not sure the removed X.25 code would have been of any use but for reading material. The AX.25 protocol spec is available from http://www.tapr.org/ in PDF format. You can do AX.25 in user space, much like PPP, with TNOS. TNOS 2.22 used to compile cleanly on FreeBSD, I know because I provided the patches to the author. I didn't keep up with TNOS 2.30 so it has a couple of gotchas and a heavy Linux bent. TNOS can be had from http://www.lantz.com and ftp://ftp.ucsd.edu/. Hint: download the Linux binaries too, that's the only way you'll get the entire runtime directrory structure TNOS requires. Maybe one day I'll submit a FreeBSD port to eliminate the configure and compile hassles. Even better, maybe someone will beat me to the port. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
