[GreenKeys] Dovetron Software Terminal Programs

[William Bytheway]

It's time to update my RttyArt program into a full blown RTTY program.
RTTYArt can currently operate as a terminal program, but it lacks the Tx/Rx
control via the RTS/DTR lines. Easy fix, but good weather is hindering
development.  RTTYArt uses the Windows serial port drivers, so it should be
WinNT, Win2K or WinXP compatible.

The WinPSK software has a nice user interface, and the source code is
available on the public domain.  I've already modified a version of WinPSK
to drive a teletype machine (i.e. BAUDOT code out the RS-232 port).The
current version can be found at
http://www.rtty.com/development/software/index.html.   Maybe it's time to
add the BAUDOT Tx/Rx portion to it as well.   I don't have code for the
soundcard decoder, so it will have to be dependent on BAUDOT via RS-232
only. Could use the MMTTY DLL driver, but haven't had a chance to look into
it yet.

Too bad it's still summer and indoor software projects take a back seat to
outdoor activities in the Sun!  The Dovetron software project will begin
this fall, rainy weather permitting.  Been busy with other software projects
that can viewed at http://www.rtty.com/bytheway, anyone interested in
viewing over 1000 satellites on a 3-D perspective of the Earth?

I'm interested on how Henry Minsky uses the Linux serial drivers to run the
UART with 5 bit chars at odd baud rates and 45 Baud.  It took me a bit of
experimentation to make Windows work with the lower baud rates.  Even then,
if I hack the hardware to fine tune 45.45 verses 45.00 Baud, WinNT, Win2K or
WinXP won't work.  Microsoft dropped C++ compiler software for direct
hardware I/O interupt driven communications many years ago.
