Would you share the one you found? I need this same thing...

Thanks,

Does your PIC have a UART? 9N1 is possible on most that do ... (see datasheet)

I was thinking on using an old f84A, but if it's easier with the USART, I would do that with one of the 18F's...

Anyway, I would be intersted in the bit banged routine to learn how to do it.

Thanks

The 84A does not but the 16F628A has one (no need to jump to 18Fs unless you want to). ALso, the UART is only TRUE mode not INVERTED - not sure what you need?
