The latest version of my shareware TeleReplica program is now available from
SIMTEL20:

pd1:<msdos.modem>
TR3-6.ZIP       Operate PC from a remote location, or monitor

TeleReplica: Remote control/surveillance of one PC from another

Purpose:
    - TeleReplica allows two IBM PC-compatible computers to be connected
      together (via telephone lines and modems, or via a direct cable, or
      via a common mini- or main-frame computer), and arranges for input
      to be accepted from either keyboard, and for both displays to
      appear identical

Common Applications:
    - access to a local area network from a remote site (for example,
      we do much of our Novell system administration (backups etc) from
      home outside normal working hours)
    - software support (to avoid the need for site visits)

Features:
    - small memory overhead on PC running applications (total around 9K)
    - common screen patterns (such as a repeating block of the same
      character or attribute) and common changes (such as scrolling) are
      encoded to improve update speed
    - obsolete screen changes are not transmitted (thus typing several
      commands without waiting for the display to catch up is possible)
    - password protection, with password transmitted automatically
    - partial automatic baud rate selection
    - support for both color and monochrome displays
    - support for hardware (CTS/RTS) and software (XON/XOFF) flow control
    - support for packet network links
    - support for COM1-4 and custom ports
    - ability to perform file transfers in the background while the
      replica PC is used for other tasks
    - support for unattended hosts, including call-back and auto-reboot
    - TR is "DESQview-Aware" and will run in a small DV window
    - detailed documentation (almost 100K) with examples of TR/TRHOST
      installation for some common applications

Limitations:
    - cannot replicate graphics displays
    - only works with text page 0 and in 80x25 mode
    - uses the standard keyboard buffer (in segment 0040)
    - causes bad "snowing" on older CGA displays
    - slows normal PC operation
    - requires DOS 3.0 or later
    - does not cope with very noisy lines

Software Compatibility:
    - almost all text applications, including:
        - WordStar, WordPerfect
        - Lotus-style spreadsheets
        - dBase, Foxbase, Dataflex
        - Turbo Pascal and C
        - WordPerfect Office
        - Novell utilities

Software Incompatibility:
    - all graphics programs (e.g. WordPerfect preview)
    - communications programs installed to use the same interrupt!
    - programs using text pages other than 0 (e.g. Turbo Debugger?)
