*Which* suggested set-up attributed to me did you read?

There are two equally valid options. The one described by Elecraft
is good for any software that regularly polls the K3/P3 combo as long
as the computer is running. The other own uses Commander's Secondary
CAT Serial port and a special cable connected to the SteppIR DATA OUT

Commander (not just the limited transceiver protocols supported by

The Elecraft Tech staff says that base of the "Y" (new connector or I hope still the SteppIR Y) should connect to the P3 PC Port and the new KUSB serial to USB goes from one branch of the Y to the PC, while the other branch connects to SteppIR controller. (P3 and K3 connect with a separate cable). Makes sense to me . . . but seems different from a Joe Subich (W4TV) suggested set up I read.
