Glad you have something working to your satisfaction!

Maybe not relevant here, but for future reference, there is a POSIX character class [:print:] that can be used in a Perl regex to emulate the C isprint() function. Throwing "non-printable" control characters to a terminal interface can cause "troubles" to say the least. Basically this character class says whether or not the "printer" can render this ASCII character on the screen.
