Subject: Temporary fix for TAC problem

I have been trying to get around the bug in the TAC software that
prevents the use of MODEM on TOPS-20 and umodem on Unix hosts.

I found a way to make it work:  BEFORE you connect to your host,
do @B O S to start binary output on the TAC.  This fixes the
problem and I have sucessfully use both MODEM and umodem today through
the TAC.  You must do this before you connect to your host or it won't
work.
