Congratulations, you have the worst of all possible combinations.  The
DMF32 is only marginally able to talk to "smart modems" due to what one
might call "fascist" modem control.  You could probably run the TB
fairly happily on the DZ, but only at 9600 baud.  You might want to
get that working, while preparing yourself for the frustrations of the
DMF32.

If you have a T1000 or a TB+ with the 5.00 roms or have upgraded,
try the S54=5 setting.  Due to some kludges in the DMF32 driver,
this should work 'normally'.  If not, you either lose the benefit
of modem control or have to use the :si: option to allow 'blind'
converse with the modem, since the DMF won't "recieve" characters
from the modem if carrier detect isn't asserted.  You also will
have great difficulty getting the "shared line" facility to work
without reasonable modem control interpretation.
