1200 BPS Internal Modem  (250-1018A)     Features      Faxback Doc. # 4780

The Tandy 1200-bps PLUS Card Modem has all the features needed to enhance
your data communications applications -- including a data output four times
faster than that of a 300 BPS modem.

This direct-connect, Bell 102/212A-type modem is designed with standard
automatic dial, answer, and disconnect features, and also has a wide range
of system configuration enhancements.  Its central processing unit (CPU)
provides operation in Hayes protocol mode.  Your modem is AT-compatible and
capable of running with Hayes software.

After dialing a phone number, the modem monitors the call and reports its
progress to your computer.  You can even control the dialing method --
pulse or touch-tone -- and the number of times the phone rings before the
modem answers.

These functions and others are controlled by ASCII (American Standard Code
for Information Interchange) encoded commands that you program from your
keyboard.

The basic operation of your modem is, in some ways, like that of a tele-
phone operator making a call.  Your modem:

* Waits as the phone rings until the dialed number is answered
* Hangs up if the number is busy or if the call is not answered after a
  specified amount of time.
* Disconnects the line at the end of a completed call

Incorporating a high degree of intelligence, the modem allows your computer
to function virtually unattended when linked to a telephone, making
possible a wide range of telecommunications applications.  Used with the
proper applications software package, the modem is capable of performing
operations such as electronic mail and shopping, central database access,
home banking, and remote-peripheral sharing.

Another feature of the modem is a built-in monitor speaker that enables you
to audibly monitor the dialing and data communication progress.  The
situation is reported visually on your computer display with messages called
result codes.
