Curious as to the setup you are attempting this with, i.e. exactly what modem are you using? One in the base of the 33 or some common external one? I'm not familiar with all the possible modem variations one might find in a 33, but AIUI the modem for the 33 at the standard 110 bps was Bell 101 standard. There's not going to be a lot to talk to out there using the old parameters. Even if someone had an auto-baud dial-in setup out there somewhere, I wouldn't anticipate it being compatible. We have a 101-standard modem (in the base of a 33) around here, but have never tried it or tried connecting it to a phone line, I'm also not familiar with it enough to know how originate/answer issues are dealt with (whether it can do both) for such 33 to 33 communication.
