You are talking to mplayer via its text-interactive interface when you are
using Print #$hProcess. You don't need to figure out how to send some key
codes because mplayer understands *commands* via this channel.

It's a shame that we haven't found time to finally prepare our mplayer-based
web radio program for public (or did we and just don't find it?).

However, you can start mplayer with its -slave switch and then look at the
command reference[0]. To, e.g., set the volume to 90%, do:

  Print $hProcess, "set_property volume 90"

To emulate PageUp, which is, by default, to seek forward by 10 minutes, you
may do

  Print $hProcess, "seek +600"

but it's really all in the docs.

Tobi
