[unix-pc.general] SCSI or ethernet via parallel port ?

merce@iguana.uucp (Jim Mercer) (01/25/91)

[ 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.

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