status of ppbus(4) and ppi(4)


[ originally posted on tech-misc; if either is the incorrect group for
this question, could someone please let me know? ]

looking for a way to have clean interface to my (PC) parallel port, I
saw ppbus(4). The manpage mentions user access to parallel ports can
be done using ppi(4), but I am lacking that manpage (NetBSD 5.1).
Googling for this turned up mails from around 2005 suggesting porting
ppi.c/.h (this is not the GPIB interface) from FreeBSD.

What is at this moment the correct way to access parallel ports (as
separate I/O-pins) from userland? If no architecture-independent
interface exists (yet), i386 might be a fallback since I use that
