Perhaps more details would help.  What output do you get if you type the
command "xmode /t2"?  How is the cable from the serial cartridge to the modem
wired?

(I've used osterm and telstar, and they seem to be able to dial reasonably.
Aside from xmode /t2 type=0, I don't think I've done anything special to the
serial port.)
