There are several commercial programs which allow you to call up
services transmitting at 1200/75 bits per second (V23).  Two of them are
Fastcom (the ST version of Vicom for the PC) and K-Comm.  They also
support viewdata services (videotex services operating to the Prestel
standard).  However, they are not PD/Shareware, and are not particularly
wonderful programs either.

Uniterm can be made to work with a 1200/75 service by using a PD program
called V23EMU.  It was written by David Jones in 1986 and is certainly
available on several UK bulletin boards.  I can mail a copy to anyone
who's interested.  I had some problems with some characters I typed not
being echoed to the screen, but I was never sure whether this was the
fault of the program or that of the complicated host I was accessing.
