I guess this may depend on your particular brand of modem, but my US
Robotics manual says this:

AT&Kn where n is one of:

0: Data compression disabled
1: Automatic detection if compression is to be activated / deactivated
2: Data compression enabled
3: MNP5 compression enabled

I don't know if this is standared for all modems, but you might try adding
&K0 to your AT init string and see what happens.

Greetings
