I didn't get any response to my query about work in progress on the
learning remote idea.  I guess I will continue to try to learn enough
to do it myself.  I need to know how to turn the modulated IR output
on and off and I can't find this info in any of the HW or internals
notes I have saved from the net.  Can someone PLEASE tell me the
address used for output and anything else that is known about the IR
transmitter?  For example, is it safe to leave it sending for short
periods of time, or am I in danger of burning a driver or the IR LED
out in my experiments as some have suggested?

Before I started thinking about this problem, I thought I saw an ftp
address for Voyager.  I didn't save it, but now I see that I might
need to understand parts of the rom to figure out how to manipulate
the IR I/O system.  Where can I get Voyager?  Will it help me
learn what I need?

Thanks for your help.
