Hi I am new to this web site. Great site by the way. I have the same receiver and S&T and had the same problem and I found some good instructions on Amazon.
Here is the tool you need.-

1. Plug in the device and make sure that drivers are installed. It should show in Device Manager under the "Ports (COM & LPT)" category as Prolific USB-to-Serial Comm Port (COM#).
2. Unzip the file you downloaded from the link above and run GPS Viewer executable file.
3. Select the right COM port (if you don't know the COM port you can find it in device manager, see #1).
4. Select 38400 as baud rate
5. Click the connect button, immediately to the right of Baudrate. It's titled "Close" for some reason.
6. When you see some codes appear in the Message section, you are ready to change the baud rate
Message should look something like this:
---,$GPRMC,013211.000,A,3355.2100,N,11754.9368,W,28.00,0.00,091206,,*26
---,$GPRMC,013212.000,A,3355.2183,N,11754.9369,W,29.00,0.00,091206,,*2E
---,$GPRMC,013213.000,A,3355.2266,N,11754.9369,W,29.00,0.00,091206,,*27
7. Go to Binary menu (next to File at the top left of the window)-> Configure Serial Port.
8. Change the baud rate to 4800 and click Set.
9. Make sure you see the message "Configure Serial Port Successful" in the Response window
10. You should now see that the baud rate has changed to 4800.
11. Click "Connect" button right next to Baudrate to disconnect.
12. Close the program.
