AT&T 705MT (multitasking terminal) -- Some of the features!

[Lenny Tropiano]

[Excerpts from the 705MT user manual]

Overview:

The 705 terminal may be operated in the following modes: native 705,
605 bct emulation, three PC emulations, synchronous, or VT320, VT220, or
VT100 emulation.

A windowing (or multi-tasking) mode allows two windows to be displayed at
the same time on the screen.  Each window can be connected to a different
host computer or to the same host computer using host resident windowing
software.  In addition, each window can be opreated in an emulation mode
different than the other window.

The 705 terminal communicates character-at-a-time (from the keyboard)
on-line.  Keyboarded data will be displayed only if the data is echoed back
(local or remote) to the terminal.  The 705 terminal utilizes the ANSI 3.64
line standard where applicable.

Your terminal operates in Full Duplex (FDX) on a point-to-point private
line or switched network.  It requires use of an EIA data source.  

The AUX port may be connected to a host to provide, along with the MAIN
port, dual host access in the windowing mode or it may be connected to a
printer to provide for hard copy of data.

Features:

The 705 MT Terminal is designed with AT&T processors and small systems in
mind.

  o Amber, green or paper white nonglare 14 inch diagonal display.

  o Smaller foorprint, styling, and ergonomic deisgn providing visual and 
    funcitional compatibility with the AT&T's entire line of PC and
    workstation products.

  o Eight built-in character sets, and a built-in PC font that supports
    various character attributes.

  o A detached, low profile 102-key keyboard for general purpose use, or a
    103-key keyboard for international applications.

  o A 10-pin modular connector to connect host or modem to the
    communications port, Port 1.  [NOTE: I was able to get away using 8-pin
    standard modular connectors with an appropriate pinout since pins 1 and
    10 can be unconnected]

  o A second bi-directional 25-pin communication port, Port 2, allowing the
    user to access a second host or to control a printer functions from the
    keyboard.

  o Nonvolatile storage for options, screen labels, and associated
    character strings.

  o Transmissions rates from 300 to 38,400 bps with asynchronous character-
    at-a-time transmission from the keyboard.

  o Set of fourteen user and host programmable User function Keys operable
    in both the Shifted or Unshifted modes.

  o Set of fourteen System function Keys operable in both the Shifted or 
    Unshifted modes.

  o Set of eight Login function keys.  [NOTE: Useful feature for storing
    login-like expect-send sequences with "security" feature to hide
    passwords from users]

  o User settable tab stops

  o Supports external modems

  o PC Terminal modem which sends keyboard scan codes to the line and
    displays 8-bit characters from a special PC font on a screen consisting
    of 25 (or 42) scrolling lines.  [NOTE: Works well with Simultask/386]

  o Screen Saver with user selectable duration

  o User selectable number of text lines (24, 25, 41, or 42)

  o Three pages of screen memory in 80-column mode or two pages in the
    132-column mode.

  o Host-to-host transfer of data when the terminal is operated in the
    dual window modem and two host connections.

  o Font downloading of the user designed character sets; one for each
    window.

  o Remapping of 80 different keyboard functions, per window.

  o Support Hardware and XON/XOFF Flow control

This terminal uses the layers(1M) xt-device driver encoding for single host
window operations.  Only two windows are supported, unlike the DMD blit
terminals.

Overall, I like this terminal, and in fact it costs less than an 
AT&T 605 bct terminal.
