I have a dedicated GPS module on the USB port of my laptop. Works great and
the Capn finds the data from the GPS without a problem.. This is a one way
communication with the laptop. GPS talker, Laptop Listener.
However, if I want to send course correction via NMEA 183 sentence, they
have to go out a serial port.
I can't seem to find a way to tell The Capn to send this info out a standard
serial port, once it finds the GPS data on the USB port.
I haven't been able to get any help for Nautical Technologies since I
haven't upgraded my software since v. 7.x came out. My laptop isn't fast
enough to run the lastest version.
Anyone have any experience with this or suggestions??

I think you're screwed. FWIW, Maptech is a lot better about things
like this, though it has other drawbacks. With Offshore Navigator,
you can specify an output port to pass thru NMEA from the GPS
and another port to output autopilot commands. This I why I favor it,
even though I don't care for it otherwise.
Does the GPSr show up as a virtual comm port or as a true USB device?
If it is the latter you have no options at all that I am aware of. I
seem to recall hearing that the GPSr sold with one of the street
mapping packages is the only one that does this. I wouldn't have
thought Capn could read this. I'm pretty sure Maptech can't
If it is the former, I still can't think of an elegant solution. You
could use use my program combined with vport software to accomplish
it, but the combo would likely cost you more than a new GPS or
Offshore Navigator and add complexity to your setup.
For those wondering how Capn works with serial ports, they expect you
to use a multiplexor, NMEA interface box, or split the serial cable
into send and receive sides so the input can go to the GPSr and the
output to the autopilot. Lazy programming, in my not so humble
opinion, but it doesn't seem to bother most people.
