[nos-bbs] Winlink and JNOS sharing the same COM port

[Jose Angel Amador Fundora]

I used net2kiss in a pure Linux system (RH 5.2, 1998-2004) ) running 
XFBB, JNOS, DXNET and ax.25 kernel services for web and ftp, on a 486-66 
with 4 MB RAM and CGA video, using two KPC-2, one for HF and another for 
2 meters and I can tell it worked VERY WELL. JNOS was running its own 
stack, which I feel is better and less prone to repeats than the native 
Linux. The details escape to me now, I would have to look for my old 
configuration scripts. I just wonder how are you going to plug Winlink 
in this scheme (maybe using a second Windows computer and a kiss link).

I assume that traffic was queued and happily alternated between FBB and 
JNOS sharing the common TNC and radio. Even more, I used JNOS with a 
window of 736 bits for some time while FBB was using the usual AX.25 255 
bits sized packets without problems. Even more, if the AX.25 user was 
too much in a hurry and tried to hog the link, timed out quicker and was 
disconnected.

Do your homework, it works!

73,

Jose, CO2JA
