Rob French 9c1a490963 Fixed comms between the Raduino and the IOP. Implemented the wrapper
that allows messages to go back from the IOP to Raduino.  I don't know
if actual CAT from the PC works currently, however.

// CAT from PC-to-IOP
//
// The general concept for IOP use of CAT is for the IOP to pass thru
// all incoming CAT data (from the PC) to the Raduino.
//
// This might change in the future, if we want to grab CAT data straight
// from the PC. That might apply to things like specific audio filter
// settings or something, but since the Raduino modes are an important
// part of the mix, I think the commands really need to come from the
// Raduino... and besides, what if a PC is not connected?
//
//
// For data coming from the Raduino, the IOP does have to do a minimal
// processing to extra any Raduino-to-IOP commands.
