Creating Bespoke output waveform

[Nicmus]

My bad. I only got Adam’s written request: swing from positive 5V to negative 5V with no need for 0V as shown in the waveform.
There are few RS 232 chips that have control pins (EN if I’m not mistaken) that will cause the outputs to go in three-state mode.
In this case a pull down resistor and one more PIC IO should be enough.

Thanks for all the help! I do need the zero fault state as this is where the signal needs to start and finish, quite right though, I didn't mention this in the original posting. I'll have a look at the RS232 option and see how I get on...
