If I understand it, possibly you could use a pty as your psudo-modem, and then run netcat on that to connect over the network. I did this many years ago. I have no idea how well (if at all) it would work on Linux. It depends on now the program access the modem, etc. Austad, Jay said: > So, I have this program that needs to dial something via a modem.
