[Elecraft] K3S-P3 Digital Cooperation

[Byron Peebles]

I'm hampered with issues using the CBLP3Y with my K3S and P3.
So, my question isn't about "getting it working", but about what 
features I'm missing.

I have the K3S RJ-45 connected to the lower connection on the P3.
Q: How do I test that this connection is "working"?

I have a USB A-B cable between my computer and the K3S.
I have a USB-Serial cable between the computer and the P3.
Q: Is this losing me any functionality at all beyond the loss of one 
additional "port" on the computer?

Right now I'm hoping this configuration loses no functionality of data 
modes between the K3S and P3.
Q: Can someone confirm I'll be able to use all K3S and P3 coordinated 
data mode functions this way?
