It may be a baud rate issue. You can change the baud rate of the
PC-to-PC link in a MENU entry in the P3 called "RS232".
Note that changing the baud rate of the K3 doesn't do anything when the
P3 is connected. The P3 will change it right back to 38400. The baud
rate that the computer sees is the one that is set in the P3 menu.

I have a Windows XP box connected to my K3 using a USB port on the box

USB-to-Serial adapter. It all works FB, N1MM Logger and SKimmer talk to
the K3
via LP Bridge and the USB/serial link perfectly, including N1MM keying
the rig.
THEN I hooked up my nice new P3 today.
It talks to the K3 FB - it gets freq data from the K3 and sends VFO
changes to the K3.
Everything else I've tested on the P3 also seems to work FB.
HOWEVER, the PC cannot talk to the K3 THROUGH the P3 - via either the
Prolific USB/serial link - or via a purely RS-232 link using the serial
port on the windows box, which I also tried.
[Just in case it was a USB incompatibility issue]
K3 Utility running in the Windows box polls the K3 via the link and the
P3 and gets no response.
Everything is set to 38,400 baud, 8 data bits, 1 stop bit, no parity.
The P3 is running the firmware which was installed at Elecraft, it was
shipped to me a week ago.
Any suggestions - please?
