Subject: Treating parallel port as serial device
Date: Tue, 28 Aug 2001 21:09:12 +0100	[thread overview]
Message-ID: <9mgtpb$mf4$1@sisko.my.home> (raw)

I'm looking to attach a serial device to my box that has only TTL level
I/O.  Since I'm more of a software than a hardware person making a
circuit board up with a max232 in is a bit risky...  I want to connect
the I/O to the parallel port.

What I need now is a driver that can read the input from a  pin on the
parallel port and treat it as serial input.  It sounds like the kind of
project that would have been done before, but I can't find anything that
even comes close.  Userspace probably wouldn't cut it as I'm reading as
9600 baud and usleep doesn't have nearly enough resolution.

Tony
