Nor have I, and I have tried at least three different ways as well...

That was the part about getting my head around the protocol I mentioned
in a previous post...  I need to find out exactly how the P3 fires
macros into the K3, then have the Raspberry Pi do the same.  After that,
it will be a snap to connect the keypad to the Pi.  I believe the Pig
Knob does it, so it is something that is doable.

Because they are not implemented the same-- that seems to be the only
conclusion I can come too in this.  You said it upthread, the two don't
accept the same command set, yet they both send ASCII...  I think you
are correct.  I suspect there is another layer of protocol involved,
which is being transferred via ASCII.  

What I need to do is to get Wireshark, (a port snooper), going and look
at the data leaving the P3...  That will answer many questions.
