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.
