Summary:  Sensitivity appears to be lower - rural phones

I have had several Courier 2400 modems at my home, and still have the last one
in addition to the trusty old Hayes 1200.  I desperately want to use 2400 baud 
when I can, especially for uucp to our work system.

Unfortunately, there are MANY times, when the Courier simply will NOT connect
to a distant carrier at 1200 baud, when the Hayes always does.  Actually, the
Courier has never connected to the systems that I have this problem with.
That is why I'm forced to use 2 modems.  The Hayes for everything, and the 
Courier *IF* they have 2400 on the otherside, *AND* the signal is strong enough.

I also note, a greater noise level (you know }}}}v}v}}}}}) with the Courier.

I live in an area about 25 miles from Cleveland Ohio, and I have not found a 
way to solve the problem. A number of Cleveland sites do have 2400 baud, and it
works perfectly as advertised, but I can't connect even at 1200 to others.

I spoke to a US Robotics Tech on my first unit and they claimed to have GREATER
sensitivity specs than Hayes at 1200 baud.  He couldn't understand why I had the
problem.  Said he'd call me back, but never did.  I have sold the various units
to other people who have had no problems.  It seems to have something to do with
the specific phone situation out here, and the Courier itself by design.

Any comments or suggestions out there.
