To anyone who has worked on the serial driver...

I need to change certain bits in one of the z8530's write registers,
but the register contains other bits that I don't want to touch.  Is
there an easy way of doing this?  The obvious solution is to have a
variable somewhere that always mirrors the last value written to each
write register (presumably an array of chars, one per register), but
the driver doesn't seem to do that now.  Am I missing something?
