Hmmm, I've had some problems where the modem would answer the phone and
just play dead!  No aswer tones of any sort.  Also one occurance of acute
catatonia that could only be reset by a gentle prod with the paper-clip.

I sort of suspect some degree of reseting to factory parameters, which
would cause the modem to ingore DTR and perhaps force a 9600 buad interface
rate.  Still, I have just (I HOPE!) stabilized my operating environment
and will see what kind of wedge factor there is when everything on my
side is working reliably.

TELEBIT:  The UUCP community would really appreciate a jumper that would
          force a "power on" reset when DTR goes away.  Our modems are
          not sitting at hand, they are off in the computer room and it
          is a real pain to have to go flip the on/off switch when they
          have decided to go to lunch.

          It is no big deal for the typical usenet site to have to open
          the case to change a jumper (like the transmit level resistor).

          Give me 1 jumper that forces power up reset on dropping DTR.
          Give me 1 jumper that write protects the EEPROM.

          The automated telecom users of the world will bless you!!!
