Version History (from when I started keeping one):

v2.0    Terminal emulator ported from Turbo Pascal v3.0 to v5.0, using a
        completely new asynch comms library.  The program now takes
        command line parameters for port number, speed and screen
        colors.  The function keys are displayed when defined.  The move
        to the new compiler improved the speed markedly and cleared up
        problems with the typeahead.
v2.0a   Fixed a problem with COM4:.  Neatened up the function key
        display.
v2.0b   Disabled the exit from the program on Control-Break.
v2.0c   Fixed the handling of the bell character, which had caused problems
        on one machine.
v2.0d   Fixed a number of problems with the dial command.  Improved the
        modem hangup, which now works more reliably, and doesn't
        automatically hang up when the program exits.  Also, the program
        now strips the eighth bit from incoming data.
v2.0e   Cleaned up the behaviour of the program when it runs with very
        little free memory.  If there is insufficient memory for the capture
        buffer the program now gives a message only if these functions are
        accessed.
v2.0f   I finally got sick of the capture to file stuff, which didn't work
        properly under TP v5.0, and was probably not very useful anyway, so
        I deleted it all.
v2.0g   Cleaned up the code a lot to make it more maintainable.  Also,
        made the default protected mode colour cyan, because people liked
        it so much.
v2.0h   Detects mono graphics adaptors and doesn't attempt to use colors
        if one is found, so inverse text now works properly on a mono
        display.
v2.0i   Fixed a problem with the protected mode coloring being turned
        off when inverse text was turned off.  Also, the display is now
        forced into 25x80 text mode if it was in another mode when the
        program started, and is restored afterwards.
v2.0j   Increased the maximum function key definition length from 10 to
        80 characters.
v2.0k   Fixed a bug which caused definitions of function keys F11 and
        above to overwrite the definition of F10, and changed the
        function key display slightly.
v2.0l   Fixed a bug which caused the program to sometimes generate a
        carriage return character when it shouldn't while trying to
        overwrite protected text with unprotected.

v2.1    Now supports slave printing, plus manual printer toggle with the
        ALT-P key combination.  If the printer in off-line, the printing
        will be turned back off automatically.
v2.1a   Fixed a bug with the ESC-F-C sequence.

v2.2    Now supports 20 function keys, keys 11-20 being the standard
        function keys combined with the shift key.  Shift-F1 and
        shift-F10 therefore no longer exit the emulator.  Also cleaned
        up the modem control (dial and hangup) code.
v2.2a   More cosmetic changes to the modem control stuff.

v2.3    Now supports a debugging mode selected with <ALT>-<E>.

v2.4    Now displays the shift-F key definitions when the Shift key is
        depressed and available commands when the Alt key is pressed.
        Removed the ALT-F command which displayed the function keys, as
        it should no longer be necessary.  Cleaned up some other bits
        of code, and implemented the Insert Line and Delete Line codes.

v2.5    Added an optional extra command line parameter allowing the
        specification of alternative print destinations.  Any valid DOS
        device or file name can be specified.

v2.6    Went over the emulation stuff really carefully, and made a few
        corrections.  The program should now work with almost any program
        that can handle a Microfusion MF30.
v2.6a   Now generates an error message if it can't write to the printer,
        to tell the user that it has turned printing off.
v2.6b   Added buffering of data to the printer and XON/XOFF flow control
        to cope better with slow printers.
v2.6c   Cleaned up the flow control stuff a bit.

v2.7    Added the ability to capture incoming text to a file (other than
        by specifying a file as the printer).

v2.8    Moved to a new asynch comms library, which gives speeds up to
    57600 bps, better flow control and break signalling, among other
    things.
v2.8a    Improved the modem hangup code, changed the dial code so that it
    hangs up the modem before attempting to dial, shortened the
    break to one second, added my name to the status line (on the
    insistence of our director).
v2.8b    Moved the send break function from the <ALT>-<B> key to the
    <CTRL>-<BREAK> key.
v2.8c    Fixed a minor problem associated with baud rates above 19200 bps.

v3.0    Added 16 pages of backpaging (by popular request), and the
        ability to shell out to DOS.
v3.0a   Fixed a bug with screen addresses containing ^Q or ^S characters
        being intercepted by the async routines for flow control.

v3.1    Implemented the esc-P (print screen).  The screen printing code
    now writes to the specified print device, not necessarily to LPT1,
        when debugging is off.  The print-screen key also sends output
        via this code, which allows for the capture of screen dumps to a
        file.  The Del key now sends a chr(127).  Chr(127)s sent to
        mufusion are now ignored.  Fixed a bug with the control-break
        key not working as expected when shelled out to DOS.
v3.1a    Tracked down a couple of places where the screen copy used for
    backpaging wasn't being updated.
v3.1b   Changed the ALT-functions help line, because I woke up to the
        fact that O comes before P in the alphabet.
v3.1c    Fixed a few places where the program attempted to use the
    backpage buffer when it was not being kept up to date.
v3.1d   Fixed the file capture code so that it warns you before
        overwriting an existing file, and offers you the options of
        appending to it, overwriting it or leaving it alone.
v3.1e    Fixed a problem with not sending characters on some machines if
    it was run immediately after another terminal program.
v3.1f    Reduced the length of the break signal from 1000 to 400ms.
v3.1g   Fixed a problem with characters being dropped while printing the
        screen, and while sending a break signal.
v3.1h   Fixed the problem with control-break being ignored when shelled
        out to DOS.
v3.1i   Fixed the backpage display function so it no longer wraps around.
v3.1j   Fixed up the shell to DOS function because some vectors still
        held the values put into them by turbo pascal, which didn't
        actually cause any problems but seemed undesirable.
v3.1k   Removed some bits of redundant code.
v3.1l   Turned stack checking and array bounds checking on for all the
        code, after a report of a machine crashing while running
        mufusion.
v3.1m   Fixed a bug with cursor positioning commands and unprotected
        text.
v3.1n   Fixed a bug with scrolling text when the character after the
        line feed was a ^G.
v3.1o   Altered the hangup function so that it tells you whether the
        carrier was dropped (for those with internal modems).
v3.1p   Recoded the back page buffer handling, because people with XTs
        were complaining about the speed.
v3.1q   Fixed a problem with the display of function key definitions.

v3.2    Implemented the <ALT>-function keys, as per the MF30.
v3.2a    Turned range checking off, which speeds everything up
    considerably, and added more documentation to the source.
v3.2b    Went over the character display code and made it faster.
v3.2c    Discovered that I had allocated a much larger stack than
    required, so I reduced it to something more sensible.
v3.2d   Cleaned up the clear to end of screen / end of line code, making
        it neater and slightly faster.
v3.2e   Cleaned up the get a character code and made it slightly faster.
v3.2f   All strings are now sent with 10ms/char delays to avoid problems
        on slow systems.
v3.2g   Turned stack checking off, which should improve speed.
v3.2h   Changed scrolling to avoid a line feed occuring if an escape
        sequence follows.
v3.2i   Fixed a couple of places where the screen would scroll and the
        backpage buffer didn't.
v3.2j   Fixed a bug in the handling of the "esc e" sequence.
v3.2k    Cleaned up the auto-echo code.
v3.2l   Wrote in a work-around for lines set up for Prism terminals to
        bypass the download an emulation stuff.
v3.2m   Fixed the "can't find the port" code so it exits with the
        errorlevel set to 1.

        after shelling to DOS when debug mode was on.
v3.2o   Minor improvements to the debugging functions.
v3.2p   Rewrote the backpage buffer handling, so it no longer needs to
        be cleared on startup, avoiding the two second delay on slow XTs.
        Increased the backpage buffer size to from 15 to 30 screens.
v3.2q   Fixed the screen dump routines so they work properly when
        viewing backpages.

v3.2s   Altered the backpaging code slightly so it stops backpaging at
        the top of the buffer.

v3.3    The Home and End keys now move the screen back or forward one
        line.
v3.3a   Recoded the backpage display routine to scroll more smoothly.
v3.3b   Slightly altered the handling of chr(12) in debugging mode
        to give a neater display.

        utility.
v3.4f   Improved the program behaviour when dealing with an illegal
        printer, and rewrote parts of the .DOC file.
v3.4g   Flushes the keyboard buffer before exiting with an illegal
        port/printer message.
v3.4h   Implemented several undocumented escape sequences (esc J, esc K,
        esc k, esc b) and fixed bugs in several others (esc <, esc >).
v3.4i   Further refinements to esc < and esc >, plus corrections to the
        handling of the backspace character.
v3.4j   Further refinements to the handling of the backspace character.
v3.4k   Corrected the esc K sequence, which should clear to the end of
        the line, not to the end of the screen.

v3.5    Implements Alt-F to send a form feed to the printer.

v3.6    Separated the number of lines option from the debugging mode,
        putting number of lines on Alt-L, and simplified and improved
        the debugging mode.
v3.6a   Fixed a bug with backpaging wrapping around when in 43/50 line
        mode.
v3.6b   Implemented the Control-Arrow keys, and the arrow keys, which

v3.6h   Fixed a problem with inappropriate cursor positioning after
        switching screen modes with emulation off.
v3.6i   Doesn't attempt to dump an image file if emulation is off (which
        won't work).
v3.6j   Stopped the screen from scrolling when protection is off (which
        it shouldn't do).
v3.6k   Fixed another minor problem with screen scrolling.
v3.6l   Renamed the Emulation function to Debug, since that's what it
        now does.  This function is still performed using alt-E.

v3.7    Implemented the RUN command, as an easy way of running file
        transfer programs without the fuss of shelling to DOS.
v3.7a   Fixed the clear field (esc p) sequence so it clears fields which
        run beyond the end of a line.
v3.7b   Rewrote the printer handling and increased the print buffer size
        to 2048 characters.

        MF30's), and removed one screen of backpaging to provide the
        required memory.
v3.8b   Removed chr(18) and chr(20) as printer control characters (they
        don't work on a Microfusion), and stopped the printing of chr(0)
        and chr(3).
v3.8c    Provides for neater handling of an illegal printer.

v3.8h   Fixed a bug with restoration of background screen color when
        returning from DOS shell.
v3.8i   Stops chr(131) being passed to the printer (this character gets
        stripped of its high bit and turns printing off).

        failing to write to the printer.
v3.9b   Put in the status information in the bottom right hand corner.
v3.9c   A really major rewrite of all the printer handling, which had
        become a real mess.  This makes for much better interfacing with
        network print queues (no longer requires timeouts), and gives me
        a much more consistent printer interface to work with.
v3.9d   Put error checking on all file close operations (which rarely
        failed, but left the program unusable if they did).
v3.9e   Added the option of retrying of failed writes to the printer.
v3.9f   Fixed a bug with specifying non-existant print file destinations
        on the command line, and cleaned up the output to the printer.
        The printer now only sends printable characters (LF,FF,CR and
        characters 32 to 126 after stripping top bit) if using esc F A,
        or everything except 0, 3 or esc F (unless quoted with a
        preceding escape) if using esc F C.

v3.9m   Removed unneccessary pausing in the INT14 version.
v3.9n   Changed the handling of esc-T with the prism kludge on so it does
        a clear to end of line if the printer isn't on.

        after shelling to DOS.
v3.9p   Minor changes to prompts in the file open routine.

        missing.
v3.9r   Codes the screen width as a variable instead of a hard-coded
        constant.
v3.9s   Allows high-bit masking to be disabled, and hence graphics
        characters drawn.
v3.9t   Uses the heap functions for the backpage buffer, allowing
        allocation of a full 64k.
v3.9u   Allows selection of any text color form the host, and adds color
        to the debugger to highlight escape sequences.
v3.9v   Fixes problems with color selection and reverse, blinking and
        intensity attributes.
v3.9w   Stops coloring protected/unprotected text when host is using
        color selection.

v4.0    Allows use of any text video mode, plus definition of a 132
        column mode by the WVM enviromental variable.
v4.0a   Responds with version number to <esc> x ? V.
v4.0b   Fixes a problem with the background color of function keys.

        environmetal variables).  Moves modem hangup function to
        <Alt>-<G>.
v4.0d   Removed confirmation on video mode select, requests confirmation
        before hanging up modem.
v4.0e   Resets the color correctly for debug mode background after the
        host has altered it.

    aborts input, and a maximum string length is enforced, and
    cleaned up some of the other keyboard input routines.

v4.1    Allows the use of non-standard interrupts.
v4.1a    Recoded the non-standard interrupt code so it doesn't drag in
