Hello Liz,
We need a bit more information here. What OS and version? What version of Xastir? What kind of radio? What kind of TNC (or software TNC)? Do you know for a fact that your Prolific (pl2303) cable is good? The reason I ask this last one is that Prolific-based cables are renown for being unreliable though they usually work fine under Linux.
Have you tried any other programs to interact with the radio via this USB cable? ?
