Is there a method to invert the TTL serial input/output on the 16F877 in software or do I have to do it in hardware? I have an inverted TTL level signal that I need to accommodate. The 877 manual isn't too much help -- but I may not be looking in the right place. It just needs a couple of transistors, but it's still a pain.
