I have had trouble with "high speed" modems connecting and getting a login unless
I explicitly set the baud rate by means of the AT37= register. The garbage you
are experiencing could be due to a baud rate mismatch -- the modems are
connecting at a different speed that that which is specified on the port. My 2
cents.
