CmdMessenger Problem

Hey all
I have recently found the CmdMessenger library and it looks to be exactly what I want. However, I am having issues with the demo code. I am using an Arduino Duemilanove with Atmega-168 on my Macbook Pro. I can successfully compile and upload the code and open the serial monitor, but when I send the demo commands I am not getting the expected output that is listed below them. I am only getting "1,Arduino ready;" or "3,Unknown command;". Nothing else is returned on the serial monitor.

Again this is using the demo code without any modifications. Does anybody have any ideas?

Thanks
Eric

Please also post the link where you found/downloaded the library. (easier for those who might want to help;)
