Well I figure it is safe to assume that anyone that is reading fidonet on a BBS
system and is in the Classic Computer Echo would know what a bit banger port
is or might be. (I should have said serial port, although its not as nice as a
real serial port with a UART) 

You might think that this is all very slow but there is some really nicely
optimized code that makes it actually very fast. (115200 bps on the coco3)

Either way the nice thing about this software is it only requires a serial
cable and some software to be loaded any way you can. (ROM Pak, off of disk,
via the cassette port and I think even through the serial itself might be
possible)

It makes it possible to do things with your coco that would normally require
lots of additional hardware so thats why I was excited about it.

Hopefully I will have time to do more with it in the future and possibly get a
coco based BBS going.
