My Furuno GPS can be connected to a PC by a serial cable. The wiring

some chartplotting program recognize this)?


What you need is called a serial to USB adapter or converter.

You can find them at places like CompUSA, Fryes, Circuit City, Best Buy,
Staples, etc. The ones made by Belkin seem to be widely acceptable, I
have never found a serial input (including a number of GPS NMEA inputs)
that would not work with the one I have.

It is a short (10" or so) cable with a USB plug on one end and a small
housing with a DB9P connector (looks just like your missing serial port
socket) on the other.

The Belkin I have (model F5U109) also has three LEDs (RX, TX, LINK) to
indicate status of the serial connection and traffic flow.

If you are into shopping around for one, try eBay. There are hundreds
of them for sale there every day. A search for "serial usb" will turn up
a bunch.
