[Coco] CoCoNet status

[Tom Seagrove]

My further thought along the emulator line was that there could be a
repository of games and apps all on DSK images located out on the internet
and sorted in a very strict manner.  I carry VCC around on a thumb drive
with some DSK images and that would free me to have access to a whole
repository of images from any net connected pc.  Could prove a fun project
as it develops over time.

Appreciate all the things you do for the community Roger, you help to keep
things alive and push the envelope....

I believe bit banger emulation in MESS is restricted to printer output
only.  A quick scan of the MESS source code (devices directory) didn't
reveal anything that would indicate support for emulation of an RS232
pak.  The VCC emulator currently lacks support for these devices as
well.

David Keil's emulator supports the bit banger, but it's not clear to
me if it handles bidirectional I/O, or output only. It also emulates
the RS232 pak at baud rates up to 19200.
