I've been using modems from Telebit for over two and a half years now,
mostly with the old Telebit TrailBlazer.  Recently, I've started running
a TrailBlazer Plus, and have started seeing problems that never occured
with the old TB.

For no apparent reason, the TB+ will freeze up and respond to
practically nothing except cycling power or the reset switch.  Under
these circumstances, incoming calls will not be answered even though
DTR is high, and outgoing calls cannot be placed because all AT
commands are completely ignored.  During all this, the LEDs on the
front behave normally -- they detect *all* RS232 signals correctly.
The only ways to get them out of this condition are to cycle power or
to use the hardware reset switch.  (Before this, I would not have so
easily considered a paper clip a "tool.")  After cycling power, the
TB+ acts as if nothing ever happened -- the configuration looks the
same as before, and 

This has happened to two modems.  The first came factory fresh as part
of the USENET promotion, and never worked properly, although its twin
(one serial number lower) has always behaved perfectly.  Telebit
exchanged the defective unit for another unit that behaved for almost a
month, and then about two weeks ago started to exhibit the same problems
as the first.

If anyone else has had such experiences, both Telebit Tech Support and
I would like to hear about it.  You can send mail to telebit!modems
(and pyrnj!romain, if you like) or call Telebit directly.
