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). -- Larry Snyder SCO Xenix 2.3.2 '386 uucp: iuvax!ndcheg!ndmath!nstar!larry Computone Intelliport AT8 The Northern Star Usenet Distribution Site HST / PEP / V.22 Notre Dame, Indiana USA Home of the fighting Irish!
