[oopic] Re: Serial Connection No Longer Working

the strange thing is I had everything working the night before; went
to bed; when I got up the next day the problem began. No changes to
the computer, software or program, or wiring. I changed battery also
before posting the first time. I didn't realize you need to connect
within the delay period though. My fear is I may have carelessly
screwed up one of the I/O's that the serial uses while playing
around late at night.

One other symptom I forgot to mention, when I plug in my testing
LEDS and reset the oopic, I/O 1 goes high and all the others I/O
stay low. the last program I loaded before all this started did a
sort of Knight Rider pattern across the first 8 I/O's so I expected
even if I screwed up the serial I/O (19,23..) that program would
still be loaded and running normally which it does not.
