try using xon/xoff flow control. Also, if you force carrier, it will more than likely keep the session established, but you might loose the ability to drop DTR after you drop the modem connection. Meaning if you abruptly hung up the modem, when there was an active shell running, the shell stays active. The next person who dials the number just drops in on the previous shell session.

i got it right.... finally!

i need to "cu -ml tty#", then changed buffer (&B0) & flow control (&H0) options from 0 to 1, then saved.

you have to setup your modem possibly to a much higher baud rate (i used 57600, i'm using USRobotics 56K faxmodem).
