	I have not had a chance to call Telebit on this one yet but will
share it with the net.  I use a Trailblazer on one of my inbound lines.
It is configured to reset to EEPROM on losing DTR.  Much of the time, it
works OK but at least twice now it has gone into "strange mode".  In this
mode, the settings listed by ATN? do not correspond to what the modem is
acutally doing.  The first time, the speaker would come on every time the
modem answered the phone even though M=0.  I manually reset DTR a few times,
check the settings and the problem persisted.  Eventually, the modem would
not answer the phone and I power-cycled it, after which everything seemed
normal again.
	The second time was not so benign.  The modem would speak ONLY the
PEP tones although it is configured to do slow tones first and PEP last.
Again, resetting DTR a few times made no change and I had to power cycle the
modem.  I am not pleased and begin to suspect that there is a "phantom" copy
of the settings that is hanging around even after DTR is dropped.  Has anyone
else experienced this problem?  I know of no workaround since that line is in
almost constant use and it is not convenient to power-cycle it regularly.
