That shouldn't be necessary. On completion, uucico would be calling dialTBIT
again to hang up the modem and reset it.

XCMALT, like dialTBIT, drops DTR for a moment or so, which is designed to have
the modem reset. Works if S52=2.

It's ATN?, which is in the manual...

There's a dialTBALL.c that was propagated, which encompasses the TB2500; the
Xenix 2.3 dialTBIT was written before that modem was sold. Do you need that?
Email me back.
