I just bought a US Robotics Courier 2400 baud modem, and I'm having some
problems with it that surprise me in light of some of the glowing reviews
of it I've read on the net.  I haven't been able to try it at 2400 baud
yet (nobody to talk to yet), but I get MUCH worse performance at 1200
baud than I'm used to.  I've tried many modems on this phone line (I used
to test different kinds of modems for where I worked), and none have given
me this much trouble with line noise.  In particular, I've used a Rixon
R212A 1200 baud modem and a Hayes SmartModem 1200 a lot lately, and both
gave virtually flawless 1200 baud performance.

So, my question is does anybody else have this kind of trouble with the
Courier 2400, or is it just mine?  I remember something about the early
ones of them having line noise problems if you got a version of the PROM
earlier than some revision level, but I don't remember what that level
was.  As an alternative to this, can anybody suggest a 2400 baud modem
that works well at both 1200 baud and 2400 baud?

Thanks...
