[aprssig] Garmin emulation

[Heaton, Brad]

Sorry for the double post.  Here is a link to the MixW serial port loop
back driver. 
http://www.mixw.net/related.htm#tncemu
It is also free (at least for ham use).  Someone will correct me if I am
wrong.  The source is also provided for this one.  This one will also
setup multiple pairs of connected ports if needed.

Hope this helps.

On the AGW site there is a link that ends up here:
http://pearsoncomputing.dyndns.org/

Then click on freeware and there is a Virtual Serial Cable Lite.  It is
free for use with Amateur Radio related stuff.

Just wanted to see what everyone thinks of an idea I had.  I've been
working
a lot with the Garmin binary protocol for my new project, and in the
course
of the development process came up with a test program to emulate
functions
of a Garmin GPS.  I found that by connecting a null modem cable between
two
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
plugin,
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
a
lot more software options.

I'm not looking forward to writing a virtual com port driver, though.
And
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
create
fake com ports, let me know.
