Has anyone considered allowing console devices to run over bi-directional
parallel ports? I imagine most of the required code is in PLIP and serial,
which unfortunately I know nothing about.

Several newer systems I have today do not have physical serial ports at all,
but all of them (even laptops) still have bi-directional parallel ports.

I suppose there may be some difficulties in exporting a "serial-like"
interface to the user apps (e.g. minicom and such), but maybe not.

Cheers, Andreas
