there should be a '[' before bufchar, right?

do i need to declare bufchar as a byte ?

Is there a loop for the serin2 alfat_tx,84, [bufchar] ?

How do i use datardy?

I was getting errors using 'read:' also, so changed it to read1:
Sorry, I was doing it from memory. "READ" is a reserved word. My bad. DATARDY is a pin on Alfat. If it is high, then Alfat has data to send. It takes about ten microseconds to change states if it is empty, or transitions high. It is a flag and should be aliased as a bit variable, just as ALFAT_BUSY should.
