Revolution Reading GPS Data

[Thomas McGrath III]

Graham,

What is the make and model of the device?

Most of the devices that I have seen (even the USB only ones) use  
serial commands or a converter to serial commands. I have come across  
a few generic USB drivers for things like the Keyspan High Speed  
Serial converter. It is a Serial to USB hardware converter. BUT it  
uses serial commands in the device, the USB driver only emulates a  
serial port on the Mac.

I have also noticed that other types of devices use the same exact  
driver. I can look it up if you tell me more.

So a little more info on the device will help.
