It works on my Ven-Tel 1200 baud, but I wonder if it's modem-dependant. It helps if you have lights on your modem so you can see what's happening (the TR light especially). Configure your modem so that it obeys the "terminal ready" signal from the computer, and uses the "modem ready" signal to tell the computer when there's a carrier. Make sure you've got a cable that carries these signals between your modem and computer (all 25 to be safe, but you can get by if you carry the right 6 or 8). Also configure your modem for auto answer. The AA light should come on. Now, when you Xenix-enable the port for logins, the TR light should come on. When you disable the port for logins, the TR light should go off. The key is that your modem will only answer the phone if the TR is on-- even if AA is on continuouly, it will not auto answer if TR is off. At least this is what happens on my modem. This way, your "enable /dev/xxxx" alone will trigger the modem to start answering the phone, simply because the TR signal will be activated. When "disable" occurs, the TR will go off, and the modem won't auto answer any more.
