The LED blinking blue is not an option that the WiModem can do. What actually makes noise when you run CCGMS? Make sure that you don't have something metallic sitting under the WiModem or touching it (shorting it). Have you tried a different power supply on the off chance that the Ray Carlsen version has an issue? The WiModem can't make the screen scramble. It could be outputting data at the wrong baud rate though, that will make it send out random junk. Did you remember to save the baud rate setting with AT&W if you changed it to something other than 300 baud? 300 baud is the default baud rate for the WiModem with the v1.97 (and later) firmware.
