I haven't personally used a Supra 33k6 so I can't comment, but I seem to
recall that Russell Brooks had no trouble calling Dave Drummond's Courier
with it, and was also seeing 33k6 connects.  Comments, Russell?

Interesting.

Is there any evidence that this is a USR problem, and not a Supra one?

Might this not be related to line quality though?  For example, my calls to
Dave tend to connect at 33600/31200 (3429 symbol rate), yet calls to
Russell's Courier quite often connect at 31200 or slightly less (3200
symbol rate).

Maybe the Supras are less aggressive than USRs when negotiating a connect,
who knows?  I'm still not convinced that the Courier has a problem in that
regard. All I know is that almost perfect lines are required for the 3429
rate.
