K3 - KIO3 and USB to serial problems

[Sean Cavanaugh]

Hi all,

I'm trying to get set up for Field Day, and as usual I'm bringing my K3.
Last time I had it set up on my laptop using a USB to serial adapter and it
worked fine.  Since then, I've had it plugged into my shack PC using a
hardware serial port, where it has been working just fine.

This time around, I can not get the K3 to talk to the laptop. I've tried 4
USB->serial adapters, including an Elecraft one (using the older Prolific
chipset) and a brand new FTDI-based one. None of them will talk to the K3,
either in N1MM or the K3 utility.

The same K3 and serial cable still work fine when talking to the PC.

I've tried a number of different cables as well. Nothing works. I've
verified and re-verified that the settings on the PC and the laptop are the
same.

Infuriatingly, I hooked up my K2 last night via the USB->serial cables I've
been trying and all of them work with N1MM and the K2.

I'm about at the end of my rope. I don't relish the idea of hauling a full
sized PC out into a field, but it looks like that might be my only option.

Anyone have any ideas of anything else I can check?

Thanks and 73,

Sean - VA5LF
