Subject: Hayes 2400 modem

I have had a Hayes 2400 modem for a week, now.  It came with a note
saying that it wouldn't work on some earlier PBX's, and if I had one,
to return the modem and a new one would be sent out in 2 weeks.

It is much more vulnerable to shot noise (appears as random left-hand
curly brackets) than the Hayes 1200, at 1200 baud.
