It won't give you a shell. >There is the program 'ct', which is intended to be used for callback >setups, . . . [edited] Well, how simple! My previous system didn't have "ct", and I had never come across a reference to it. But having received this suggestion, I found that I do indeed have "ct", and it does exactly what I wanted!! In my case, after I dial in and log in, I simply exec a script which runs ct in the background, tells me to disconnect, and exits. I disconnect the modem, and wait a few seconds, until ct calls me back. When modem connection is established, ct starts a getty, and I can log in again! Fantastic. Thanks for your help, Willy! Hope this is of use to others as well. -- +-----------------------------------------------+-------------------------+ | Hershel Belkin hp9000/825 (HP-UX)| ...!lsuc!teecs!belkin | | Test Equipment Engineering Computing Services | Phone: 416 246-2647 | | Litton Systems Canada Limited (Toronto) | FAX: 416 246-5233 | +-----------------------------------------------+-------------------------+
