In the PBP3 manual there is this paragraph:
SHIFTOUT is a software-based command and does not require that the target device have synchronous serial capability. The ClockPin and DataPin parameters...
Probably yes. But it depends on how you write code.
Looks great!
BAUDCON does not appear in 628 or 628a data sheet.

Since I've almost finished development of this clock, including hardware side, and I want to post an instructable, I want to make my code a bit tidy also. I have made several screen update routines,...

Your serial circuit diagram/connection details would help - what is connected to the TX line ?
Is it just TX that is the problem ? have you tried RXing ?
Have you tried lower rates ?
Do you...
By Xtal, do you mean that an external 4Mhz crystal with two caps like 22pf?
