»%t«DO»#« has a complete set of »ye«communications functions»#« which allow you
to perform »wh«asynchronous ASCII communications»#«. These include »gr«DEC
VT100 terminal emulation»#«.
.pg
»%t«DO»#« can communicate with most modems or over direct connections at speeds
between »ye«300»#« and »ye«9600»#« characters per second (baud). It is not intended
to provide you with complete telecommunications functionality. For
example, »%t«DO»#« does not have a directory dialer (although you COULD write
one using the script language).
However, »%t«DO»#« can provide basic communications functions to extend
the functionality of your scripts.
.pg clr
Since we do not know the capabilities of the system on which you
are running this tutorial, it does »re«NOT»#« include a working communications
demonstration. However, all communications functions are described
and the script »gr«COMM.SCR»#« contains a functioning communications script.
You will have to modify »gr«COMM.SCR»#« to fit your setup, however, it will
provide basic communications functionality and demonstrate some
of the features available in the »%t«DO»ye« script processor»#«.

All »%t«DO»#« communications scripts have the same basic requirements.
the following statements are the minimum requirements to have
a full-screen interactive communication session using »%t«DO»#«.

»ye«/INITCOM . . .»#«
The »%t«/INITCOM»#« command initializes the communications parameters
and sets up the buffers used for communications. »wh«It must be
executed »re«before»wh« any other communications command.»#«

»ye«/TERM . . .»#«
The »%t«/TERM»#« command starts the actual interactive session. Pressing

The »%t«/CLOSECOM»#« command »re«ends»#« the communications session and
releases the communications buffers and other resources set
up for the session.
