[Elecraft] K3 and the MRP40 CW Program.

[Gavin Keegan]

Can anyone help or advise please ?  I would like to install the MRP 40 
program on my shack computer and send and receive CW via an RS232 lead 
connected to my K3, but I already use an RS232 lead connected between 
the K3 and the controller for my SteppIR antenna.  Can anyone advise how 
I can connect both the shack computer and the SteppIR controller to the 
K3 RS232 socket and use both items at the same time ?  Gavin Keegan G6DGK
