The solid light means the jag has a signal which infers communication. Seems like I was getting this problem earlier, but I didn't actually have communication. Turned out I had a pin wrong in my RS232 adapter cable.

If the led remains solid after you press the assign button, it is not getting the command for some reason.

Can you down load the Version 92 firmware? Is the temp updating? That would eliminate some possibilities.

Some computer comm questions. Look in system settings is your RS232 port really comm 1? What kind of RS232 port are you using? Do you have another program trying to use the com port. RSlinxs (Allen Bradley & the old Palm software was real bad about that. Do you have a IR port.
