Hello,
The SEROUT2 command is a bitbanged routine for async communications. It allows you to use "any" pin on the PIC as your "serial port" but it has the disadvantage of "blocking" the processor while it's doing its thing - which doesn't seem to present a problem in your case - and it allows you to set the number of databits, ie 7 in this case.

Given the two PICs you have, definitley go for the 627.
