Framing error if I disable transmitter after shift register is empty?

Since the output on that specific chip will remain as driven output, and if you insist on using this, a crapy solution maybe to add a diode at the output before the pin is connected to the bus. ...

I "like" the 16F1937, but I have no allegiance towards it (I only have 15 on hand, I'll keep them for "something else"). I'm starting the slow/annoying process of choosing another PIC, with added requirement for ODCON register.

... The chip that you found to be faulty, may have been hit by ESD charge. Are you familiar with ESD protection? Are you taking measures when you handle ESD sensitive components?

I don't have carpet, and that's the extent of my ESD protections. I think I somehow messed it up when I first powered it up on the breadboard. It's a real possibility that I applied power to the wrong pins.
