Bob, My experience is with the LEA-5T but I am confident that the same applies to your the LEA-6T. My recommendation is to make the changes with the USB interface and the U-center software (available at no charge, download UBLOX). If the interface is not provided for it is as simple as a usb cable two 22ohm resistors and a 3.3V regulator and the appropriate capacitors. Need further help let me know, I'll provide additional details.
Another way I have done it is to remove the chip which normally talks to the GPS via the serial path and insert the appropriate serial converter board temperarily, usually only three connections (Rx, Tx, GND) and again use the u-center software. -- S.

I had assumed that I would have to discover (or know) the baud rate already set on the LEA-6T in order to change it. But it appears that the LEA-6T can receive messages at any baud rate, but you need to send baud rate change commands at the baud rate you wish to change it to. Can anyone verify if this is the case? I can't find anything in the documentation I have that addresses this question. Maybe it's just obvious to everyone else?
