I bought a one-for-all remote that I drove from FreeBSD just in the last year or two. You might try www.smarthome.com. I bought the remote, cable, and docs for how to use it for under US $100. They also have RS232 learning IR devices for $180. Expensive, but I wasn't willing to do the electronics work. -Chris > -----Original Message----- > From: David Kelly [SMTP:dkelly@HiWAAY.net] > Sent: Tuesday, June 15, 1999 8:48 PM > To: Josef Karthauser > Cc: Roger Hardiman; multimedia@FreeBSD.ORG; hackers@FreeBSD.ORG; > sos@FreeBSD.ORG > Subject: Re: IR Remote for AverMedia and FlyVideo > > Josef Karthauser writes: > > > > I've got a phototransistor plugged into my DTR line on the serial > > port.
