[Coco] OS9 Boot SDC

[phil pt]

Sounds good. The Commodore 64 has bbs system that can be access using
telnet to access their systems over the internet. You might want to take a
look at the serial bits used on the commodore 64.

The timming routines can be used to control the data flow and when the
events kicks off each time the sub routines can be used to send and receive
the data as well check to see the rs232 pack is full. If the buffer then is
full the dats cound be stored in the drivewrite buffer until it comes
available the next time the timer event kicks off.

Most all the object programming languages support it like vb.net which also
supports ful winsock control on data arrive ect... events.

I would try and use the same peek and poke address as the old rs232 pack to
check for carrier, if data is ready to be send and data arrive.  A lot of
software for the coco source code is not available but happen to have one
of the bbs source code that runs under Os9 Level 2.
