I have code for a software UART in my RS232 tutorials, it uses seperate input and output pins, but could easily be altered to use the same pin.

Why do you need it on the same pin?.

I meant it to be in the same port as in port b, dont care about the pins, just the port(I have only port B spare)

thanx

In that case the tutorial code is fine as it is!.
