[mythtv-users] Front-panel controls for MythTV box?

[Zagaroth]

I hav tryed to do something similer and have found that you can wire they
stright up to the serial port if you want but then you hav to poll the
serial port for changes all the time... another way that i just though or is
to wire it up to the PIC microcrontroller and change the key presses into a
format that LIRC could read... then plug it into the 2nd serial port and
treat i just like a remote..

Hope that helps...
