I just installed the drivers for my 634 USB device and the computer is seeing it and it is lit up. I am trying to use CrystalControl. I for some reason connot find the COM number I am supposed to be using or the baud rate... can anyone help?

Go to the device manager. Look under the "Ports (COM & LPT)" section. There you will see what COM port the USB LCD is assigned under. Set your software to the same port.
