Yes, I second that, as I did the same thing with my eeePC.
First I had an old Dell, that I simply used as serial RS232
, DB9 connection (you only use 3 of the 9 pins...google an image of "rs232 pinout" to see which ones...I think it is pins 2, 3, and 5.)
I was actually surprised that it worked within like 10 seconds of hooking it up (was using SeaClear at the time) without any issues at all (I think the only thing I had to do is activate the appropriate Com port, and the SeaClear instructions told me how do that.)
Then I switched to a eeePC. I simply bought a $10 Serial to USB pigtail, pluged it in and it worked. Again, crazy...I am usually never this lucky with computers
You could simply use the Receive from your GPS
, but I used both Receive and Transmit, in case I want to send routes to the GPS
. I read that it's not best to combine the grounds from both the Recieve and Transmit (into pin 5), but I think I did, and it works fine.
