OK, so after a brief hiatus, I'm back at work on this device. I have all the codes researched and configured (I wrote a Perl script to send these commands to my receiver) and have just created the device in LinuxMCE.
Here is the command I think I have it attempting to send for #192 On:
<$"ISCP\x00\x00\x00\x10\x00\x00\x0\x01\x00\x00\x00!1PWR01\x0D\r"$>
Here is the log entry generated:

Now, how do I go about debugging this? I've tried
/usr/pluto/bin/MessageSend localhost 0 62 1 994
but that gives me nothing extra. Thanks!
