It's worse than that.  With modern (preemptive, multitasking)
operating systems, it's becoming difficult to precisely control
the bits of a serial or parallel port even if you have native
hardware.  We need something like a stream-based semi-realtime
bit-wiggling protocol, and then it could be run over serial,
USB, IRDA, Bluetooth, zigbee, or ... anything.  Unfortunately,
I'm not sure that anything short of some sort of code interpreter
on the destination would do the trick.  (Of course, since such
an interpreter has been shown to fit in a 16C54, maybe we should
juts byte the bullet and write a spec for such code...)
