I'm using a 12C508 with one of it's output pins tied directly to the RxD
pin on a PC's printer port (i.e. 0..5V levels rather than true RS232 --
but works without problems since minimal cable lengths).
Even though I set this output pin to 1 within 10us after reset, I still
get <Break>s on the PC every time the PIC resets on the WDT (at 9600bps).
Why?
