I had 4 com ports working when I was using xenix 2.3.2. When I installed the
xnx155b upgrade which brought xenix up to 2.3.3, they quit. I am assuming
this is what happened to you. First of all, make sure you comment out one
unused port discripter in your sioconf.c file. I think there is a fixed
number of available configurations. I could be wrong though. Anyway, it
won't hurt anything. Next, in your link_xenix script, you will see a line
which calls ld. put a reference to your sioconf.o (../io/sioconf.o" file
before the reference to vpixio.a library. this should get you going. This
bit me as well. Bela Lupkin from sco pointed this out to me. (thanks sco)
