 Supra will not connect to Courier at 33.6 according to Supra Echo
 contributor:

If the calling modem is a USR Courier then the Symbol rate of 3429 is
obtained and a 33600 connect is possible.
BUT if the Supra is the Calling modem then the USR defaults to 3200
Symbol rate and the maximum speed is 31200.

I think USR does know this (or they will soon) and hopefully we should
see a .SDL flash update for them though they could be waiting for the
ITU to approve the V34+ first before doing anything..

I have about 5 Courier around me here (within 10 miles) all connect
with the 3429 rate to me but when I connct to them I get a 3200 rate.

If the USR disables the 3200 rate then it is possible to get a 3429
rate connect, but this 3200 rate is probably the most common used rate
and is needed for modems that don't support the 3429 rate (yet)

There is no way of getting a higher rate until USR sort there problem
out.
