I'm trying to build a little serial backpack for an LCD screen (16x1)
and am already using the external interupt for the busy flag.  anyway I
was wondering if anyone had any code for a serial in routine that used
timing delay loops.  I would like to keep my standard 4MHz crystal
instead of that wacky 3.6838 or whatever that one is.   Do the delays
have to be accurate when coming into the pic?  I have a serial out
routine that uses these loops and is slightly off, but still works with
my computer.  thanks
