I had to use a level converter (MAX232) to make the communication work.

Looking at some posts, I have understand you connected your PIC directly to the PC's serial port (= without converter)?

I must be wrong, no?

Nope not wrong. I have pic output GPIO.0 connected to a 1K resistor then to serial pin 2 and GPIO.1 directly to serial pin 3. Serial pin 5 to ground.
Also have a 0.1uF from pin 1 to 8 of the PIC + and ground. Thats it using the last bit of code Mister_e posted and its working fine.

I should already be in bed now, I'm crashing now but if I can help I will tomorrow.
