    are you switching back and forth between terminal emulators?  or
are you using a midi interface on the serial port?  i think that if
DTR happens to be high when vt100 (or anything else that uses the Exec
serial.device interface) opens the serial device, it will be restored
to that state when the device is closed.  thus, if you want DTR on all
the time, you could write a short hack that would poke the 8520 port
that controls DTR.  this would "break" the hangup() code in vt100 v2.2,
but you could use +++/ATH0 to hangup manually.
