1. Is there a handshake? If not
the phone number is probably wrong in some way. Are they trying to turn
off call waiting the wrong way for their telco? Do they have call
waiting? Do they have pulse but are trying to dial tone? Etc...
2. If there is a handshake check their
connectoid and network settings. If all looks good it is probably a
handshake error. Make sure the correct modem is selected and setup.
3. Try upgrading the firmware. To
get them on the net in the meantime try lowering the fifo buffers, setting the
max speed to 57600, and adding an init string. Try an init that will
retain v90 first, but if they just want to get on and download their drivers try
setting v34. Uninstalling and reinstalling the modem can sometimes help as well.
