Sounds like the same problem the early Motorola 56K modems had. Problem
was stated to be a defect in the Rockwell chipset that necessitated a
recall of ALL the modems. (These were not flash upgradeable) I wonder if
Hayes got the same bum chips, or this is a new batch of bum chips? Or
this is actually a PM-3 problem?

On another note, we just had a customer come in showing off his Zoom
K56Flex modem. Flash rom upgradeable, also with a Rockwell chipset.
Wonder if he will also have problems with our PM-3's? (they are at the
end of our ringdown, after a couple hundred USR Courier V.everythings).

Another reason why we are going to have to have a list of tested
compatible modems by brand and model. Or at least a list of problems. It
is all well and good that we won't have 56K modems and code until June or
so. (We aren't officially supporting 56K until there is a standard) But
the customers are out there buying X2 and K56flex modems now despite our
warnings not to. I bet several of you are in the same situation.
