subject: USR Courier V34 problems

Hi folks, I have been given a USR Courier V34+ for trial for 
1 month.  1 week has passed already, and would like to know 
if anyone has suggestions, which I can try in the course of 
the next 3 weeks.  At this stage, I will not be touching the 
USR Courier with a barge pole.  I had far less problems with
my Spirit Thunder, which I knew for a fact was a load of
rubbish.  At this stage I am looking at getting either a
Netcomm or a Yum Cha V34 modem.

Oh, my Spirit Thunder died in a lightning attack, which is
the reason for the upgrade to V34.  Some of these problems
should be able to be verified by anyone with a USR Courier,
e.g. numbers 1 and 5.  For you to get the others you need
to be called by the same people who are calling me.  I have
sent the people who are getting the problems off to hassle
some other USR Courier owners that I know of.  Note that I
didn't have any of these problems with my Spirit Thunder.
I had a different set of problems with it.



              Problems with USR Courier V34+

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. Regularly getting 26400 connects with a Netcomm instead of
28800.

3. 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.  Yet the ATI6 does not show that
a retrain was requested.

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

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

6. A Spirit Thunder is getting connects with me at 2400 bps far
more often than 19200.  1200 bps connects too.

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

8. Failed to connect to Hayes modem at all.  Very weird sounds
coming out.  No problem when I was using a Spirit.  This actually
happened with an older revision of the ROMs, and cannot confirm
at this stage whether it still exists because the modem was 
taken offline so that I could connect.

9. A Netcomm modem (PCMCIA or something) gets connects of 1200, 
2400, 14400 and 28800 with me.  This also happened with the
older ROMs, and the caller has not called since I changed ROMs,
so cannot confirm the continued existance of this problem.
