Richard, Thankyou for the reply. I will need to digest what you have written. I will get back to you.
One question ,What does the serial + command do? That looks like promising path to tread.

The compound += operator is used to add something to an existing variable. So:

Code:

      serial$ += CHR$(BGET#chan%)

is shorthand for:

Code:

      serial$ = serial$ + CHR$(BGET#chan%)

(it executes a little faster too). In this context you can use it to build up a string character-by-character.

Richard.
