[ forgive me if this concept has be shot to hell already ] there exist on the market a number of "thingy"'s that attach to the parallel port. most of them are called printers. 8^) but there are newer gizmos which can, with drivers under MS-DOS, adapt the port into a SCSI controller or an ethernet NIC. on the unix-pc/CT miniframe, you can write loadable device drivers. could a driver be implemented to use one of these devices? on another note. could a device driver be written to do SLIP on the serial port(s) and interface with the pty's? just wondering. -- [ Jim Mercer work: jim@lsuc.on.ca home: merce@iguana.uucp +1 519 570-3467 ] [ "Clickity-Click, Barba-Trick" - The Barbapapas ]

Nope. The 3B1/UNIXPC's parallel port is NOT a programmable I/O device with
data-direction registers; it is a printer port, period.
