I now have patchkit 0.2.4 installed, and I am trying to get the sio
ports to work with a modem.  I have been working with this for a
while, and am finally asking the net for help.

My system is as follows: 

386bsd patchlevel 0.2.4
80386 pc with 8m ram, 2 serial ports on mb.
Zenith 2400 baud modem (Hayes compatable)


I have not been able to get the sio ports to work with my modem. 

I noticed that the instructions for comcontrol indicated that the
tty and cau devices should be major device 8 - since sio uses major 
number 28, I have set them up with that (tty00 28,0 - cau00 28,128).

comcontrol seems to work, and if I echo something to the device, I 
see the rd and sd lights flash, but I am unable to control the modem 
(i.e atz ats0=1 have no effect).

I have set up the tty00 with stty to 2400 baud, -clocal, and all
other settings are at the default.

If I try to set up the port with /etc/tty , ps will show that the
getty is running, but when I call the modem, I get no response.

I am new at setting up a comunication port with unix, so any help
would be appreciated.
