Could you send the source code to me? I'll take a look if it is simple.

I have the following question: Let's say that I have a block of user
memory which I've mapped into the kernel, and would like to send on a

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 electroni
