the same. I did not have a schematic with the pin #'s
in front of me. Those pins are 35, 37 and 39
respectively.
So what you are trying to say second then, is that
this is normal operation for the oopic? Then what
about I/O 21, is it independent or is it also tied
into the internal RS232?
Do you know of better a schematic that shows this for
the oopic-s board?
