I see, in my notes, dating back to late 90's (97ish) support for
PLIP in FreeBSD. But, that's a full-fledged network interface,
not just a "file transfer mechanism". I know it was capable of
working with SPP's so it required a special cable (to push
nybbles across the wire). I am not sure if it supported
any of the "enhanced" printer port capabilities, though.
My most recent SCO release predates this, IIRC (I don't actively
follow SCO's product :> ) but I don't think it has any of
this sort of support.
I think PC-Anywhere (?) supported this on MS platforms many
years ago. As did MS's own protocol.
But, I am not sure if this ever made it out of the MS world... (?)
