Try setting register S52 (DTR Interpretation) to a value of 2. When
DTR is turned off, the modem will disconnect the call (if in progress),
and reset itself to the Configuration A/B parameters based upon the 
external switch setting. See the telebit manual for more details.
This feature works quite well, since I can have my tip and uucp
scripts be very dynamic, with option setting, knowing that everything
gets reset when done.
