Help needed

[Ying Xie]

I just bought a Pro* 2400 internal modem. It dials the number of the
mainframe(I can hear the dial tone) fine but after that nothing happens.
The software I am using is Procomm. The manual for the modem is so 
confusing that I can hardly know what is going on. I hope that somebody
can point out what the possible reasons are. 

Thanks in advance!
