[Elecraft] Setup P3, K3 using Microkeyer2

[Kurt Wiksten]

I have just bought the P3-kit to work with my K3 S/N 23xx. 
According to the P3 manual, the Male – Female DE-9 cable 
should be connected between the XCVR connector and K3:s
rear panel RS232 connector.
My present setup for the K3 is with Microkeyer2 as I am 
working a lot of contests using N1MM+ for logging and Logger32 for DX-ing.
The station computer is a HP Laptop, using one USB-port.
The Microkeyer2 USB Device router is setup so that 
K3 CAT and PTT  is COM3, Winkey CW is COM 5 and FSK is COM 6
and there is a Microkeyer2 cable connected to K3 RS232.
The question is , can I move this cable to the P3 PC connector
in the back of P3 and communicate via the P3 to the K3 ??
Do I need to setup unother COM-port for the communications P3 to K3??
It must be somebody out there who is also using Microkeyer2 together with 
K3 and P3!!
