I understand that you're trying to make a serial printer driver for ???

the calc runs @ 4 mhz, so, I guess about 4000000 cycles.

ehm, didn't it wait for the next interrupt, and then continue,
interrupt was about 1/260 th second if I am correct

crappycodersguild.cjb.net ;-)

Hmm, I haven't checked out group files, but I guess you need to rewrite the header
