:What, huh??  I've never seen anything shove bits as fast over a serial line
:as you can over a parallel line.  Try comparing the time to download fonts
:to LaserJet II on parallel vs. serial (even at 19.2Kbaud) sometime, and see
:if you don't want to keep your parallel port around when you get a laser 
:printer.

	Ahh hah haa ha.... Man, you haven't seen serial lines.  There are
	a couple reasons people use serial rather than parallel.  When I
	design *any* custom communications hardware, I always use serial.

	(1) You can do it with a twisted pair, and only two drivers on either
	    end.  Or at worst three wires (full duplex operation).  With 
	    full duplex I usually run data communication synchronously.

	(2) You can run the things *fast* ... So fast, in fact, that in
	    many cases one doesn't even need to check the TxRegister Empty
	    bit... the bits gets shifted out faster than you can write the
	    port.

	It isn't my fault idiot manufacturers are still running their
	serial ports at 19.2KB.
