I belive the correct approach will be to combine both of your examples by using single quotes on the command line -- to keep the shell from catching the '@' and '$' (and backslashes) -- and backslash escaping the special characters to keep the Tcl interprater from seeing them before they can be passed to the device.

I did not even consider that the first time.  Escaping special characters is not one of my strong points in the shell.  I'm constantly having to tweak my grep strings for that very reason.  Also, please post to the list next time so everyone can benefit from the knowledge.  I know when you hit "Reply" that is not the default behavior, but the knowledge transfer is very useful.
