Display all the command window text in static text GUI

I am using a function which displays something for query from serial interface and executes only if i enter the correct port being displayed in command window in my serially interfaced device. So it means i cannot use diary as the function command will not finish unless correct port entered. Instead something will appear in command window and i don't know from where that string comes from the function. I simply want that command window content displayed while in function, to be displayed directly in static text so that it may complete that function commands.
