I am using the Intelliport AT8 and had the same problems until
installing the new drivers and firmware.  Have you checked your
cable wiring?  Are 8 & 20 crossed, 2 & 3 crossed and 1, 4, 5, and
7 straight through to the modem?

Make sure you are using the ports for dialout (/usr/lib/uucp/Devices)
as ttyi00 - since inbound calls will be using the port at ttym00
(if you have it set up for modem support which waits until CD
goes high before sending data out the port).  

Did you change anything in your /etc/ic_control file?  I ended
up changing the buffers to 50% on the modem ports.

Also, check your modem to make sure you are not enabling the modem
to provide DTR.  If you disconnect the serial line will DTR
drop?  If you run /etc/ic_init will DTR drop (it does for me for
a second or two than comes back up).
