Has anyone out there any experience on how to setup the 7300 modem to connect to a callback system. The way it works at ISI: - dial a number - give an access number - hangup - you are called back - connect I would like some help in how to set this up on 7300 Unix PC. Reply to net, or e-mail to najjar@venera.isi.edu Thanks.

We also have a system like this at Villanova University. I have hacked together a program which is not as reliable as I would like it to be... I would like to work on it some more and then if I get it to work reliably, I'll make it available to interested parties. Now, it almost always works the *second* time I try it... (i.e. I invoke callback, login to the remote machine, it calls me back, the modem answers, and I hang. I then kill the processes, and try again. This time it works as intended! ) I must not be setting up something properly in the modem which "fixes" itself when killed?!? Also, I haven't yet figured out a way of forcing the modem back to VOICE:IDLE after the program exits.... Ed Hepler elh@vu-vlsi

I can tell you how I set it up for a friend of mine on a similar UNIX system, it sounds as if it would work on the 7300... I defined a login which ran a small program instead of bin/sh. The program made a uucp request to the remote system, and the called system (my friends) then returned the call. Except for the trivial program it was all software on most systems. The program was something like system("date|mail remotsys!nosuchuser") -- bill davidsen (wedu@ge-crd.arpa) {chinet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me
