Problems with USR Courier V34+
              
Note: Supervisor Date = 1995-07-18
      DSP Date        = 1995-07-05



1. After receiving an "AT" command at a particular baud rate,
the modem does not adjust to that baud rate, and instead stays
at the rate at the time of last "AT&W".

2. After a call, if I issue an "ATI6" straight away, I do not 
receive statistics (unless you call "0" a statistic).  If I put 
in some delays, and change the syntax, I do, as in "~~ATI11|~~ATI6|".

3. I am not connecting to other V34+ modems at rates above
28800.

4. Modem is initiating a retrain straight after each connect,
even with V32bis modems.  I would expect that the initial
negotiation would have figured that out, no need for a retrain
on every single bloody call.

5. Having problems talking to a Supra modem, 50% dropouts where
previously there were none (with a Spirit Thunder modem).

6. AT&F1 sets S56 equal to 16 instead of the default of 0 listed
in the manual.

7. A Spirit Thunder is getting connects with me at 2400 bps far
more often than 19200.

8. USR to USR connect failed due to a retrain failure.  Also,
USR to USR is showing 21600/2400 as the connect rate.
