Setting Up Communications; Connecting The Computers; Hardwiring The Computers - Tandy 600 Owner's Manual

Setting Up Communications
Before you can communicate with another cQmputer or automatically dial
a phone number, you must first set up communications. Setting up Telcom
communications is a two-part process: connecting the two computers and
setting the communication parameters.
Connecting the Computers
The first step in setting up communications is connecting the Tandy 600 to
the host. You can "hardwire" two computers that are side-by-side or
connect two computers over a te!ephone line.
Phone line connections can be direct, through the Tandy 600's built-in
modem, or indirect, using an acoustic coupler or other modem. A direct
connection is much more reliable than an indirect one, and usually
necessary for automatic dialing.
Hardwiring the Computers
If you plan to connect to a host computer that is nearby (up to 100',
depending on the length of your cable), hardwire the two computers.
I. Connect a DB-25 RS-232C Cable to the RS-232C port at the back of the
Tandy 600.
2. Connect the other end of the cable to a Null Modem Adapter, then to
the host computer.
