Hi Fred:
The Mini SSC does have a TTL-mode, but it needs inverted data i/o mode.
Rather than figuring out how to do that in s/w I just used the MAX232
because it was easy and it made debugging easy into a dumb terminal program
on my PC.
I've had several requests, so I'll definitely post the code and diagram to
the group.
Cheers,
- Mike

Doesn't the Mini SSC have a TTL-levels mode, making the MAX232
unnecessary?
Please send your serial output code, though. that would be good to
distribute.
