Hans,
What Christopher Prosserhas stated was correct, and this is exactly
what Vadim Gerasimov does in his HDBL windows program.
And it is also the technique used in my HB_Buffalo downloader program
for programming the HandyBoard with a Buffalo type machine code
monitor.
http://132.234.46.5/Programs/HBoard/Index.shtml
My downloader was written in Borland Delphi, yet I am familiar
with Borland-C. I can thus help if needed.
I would be interested in seeing this project come about. Keep us
posted!
