I haven't seen anyone else answering this yet (scanning subject headers),
so I'll do it.

Somewhere in my archives, I have a fairly good program that was written in
assembly language for the Motorola MC6800 about 20 years ago.  I would like
to "get around" to converting it to PIC code, but haven't found the time
yet.  The program does both send and receive from/to an ASCII terminal.
The send speed is determined by external interrupt rate, but the receive
speed is self adjusting and has been tested from under 3 WPM to well over
100 WPM and as written, will adjust between these extremes within one to
three characters.  Only problems are: requires a "clean" input signal from
a receiver (won't tolerate noise), and not a great amount of tolerance in
the dot/dash ratio or interelement/intercharacter spacing (great for
improving one's "fist").

I see no reason why it couldn't be converted to PIC code, even taking
advantage of a PIC's timer.

This program was demo'd at the Dayton Hamvention (Dayton, Ohio) back around
1976, and also was converted to use a MC6802 and 6847 (video display
generator) and used in a couple Boy Scout expos.

If you are interested, I can dig out the source code and send it to you.
(Please email me directly instead of cluttering up this mailing list.)  It
was also published in the ancient 6800 Users Group Library, but unless you
or someone you know just happens to have that sitting around gathering
dust, it would be hard to find.

Juan,

If you downloaded the PS+ update file and installed it, you
will find the hex file in the MPLAB directory.

The PICSTART-PLUS hex file is now shipped as part of the MPLAB 3.12
    installation.  Once the user installes MPLAB V3.12 and answers "YES"
    to the "do you want to install PICSTART-PLUS" question, the
    PSF12000.HEX file will be installed into the MPLAB directory.
