Back to my original problem, the PIC16F88 is supposed to be "factory calibrated" to 
typ +/-1%, worst case +/-2%.... I'm observing 5% (+/-2.5%) variation between a 
handful of PIC's at a fixed temperature.

The question is if the initial "factory calibration" value needs to be retieved from the 
last location in program memory using a CALL like some other PIC's - the data 
sheet simply doesn't say.

BTW, Thanks for your other comments and explanations about the 2 stop bit 
scheme.
