Hello,
I have a problem to connect with a modem from my Linux machine to a Linux server (modem is working, as other people can connect). My modem is an external one, GVC, 33Kbps. The problem seems to be that my modem does not understand when it gets connected to the remote modem. First of all, to dial I have to use ATX1DT instead of ATDT, I do not know why. After the modems are connected, the "typical noise" comes and it never stops. I never get the login prompt. Below is the relevant part of the log file in the server (modem answers after 4 rings, thus the RING string).
Any ideas about what command/string I should send so the OK/CONNECT talk is understood?
