On the AGW site there is a link that ends up here:
Then click on freeware and there is a Virtual Serial Cable Lite. It is
free for use with Amateur Radio related stuff.

Subject: [aprssig] Garmin emulation
Just wanted to see what everyone thinks of an idea I had. I've been
a lot with the Garmin binary protocol for my new project, and in the
of the development process came up with a test program to emulate
of a Garmin GPS. I found that by connecting a null modem cable between
serial ports, I could transfer waypoints to and from any mapping program
that supports Garmin protocol - which is most of them.
I think something like this might be easiest to deploy as a UI-View
at least initially. It wouldn't be completely seamless from the mapping
side, since you'd have to manually start transfers, but it might open up
lot more software options.
I'm not looking forward to writing a virtual com port driver, though.
all of the commercial loopback drivers I've seen start at $100. In
Unix/Linux it's absolutely trivial to set one up, but it could be a real
pain in Windows. If anyone knows of a cheap (or free) solution to
fake com ports, let me know.
