[comp.dcom.modems] T2500 at Bell 103 modulation

dts@peanut.UUCP (Daniel Senie) (03/19/91)

I've been trying to dial into Compuserve at 300 BPS, due to better rates.
For certain uses on CSERVE, I find 300 is actually fast enough, since I can read
as fast as the characters come out that way.

The problem I'm having is that with recent revs of the T2500 ROMs (6.01 and
7.0) I have been unable to complete Bell 103 calls. The modems answer and
think they're happy, but no amount of playing with baud rates/parity/etc.
will make anything other than garbage come out.

I tried the same thing with a Microcom AX/2400 (a basic Bell 103/22/V.22bis
MNP4 modem) and connected just fine. I suspect I am getting a modulation
other than Bell 103, perhaps V.21, but have not found a way to correct this.

Any ideas?
