Your code is all but unreadable so you might try again tp post it and format it appropriate, pasting it as plain text inside a [xcode=vb] tag.

As for the question, think about it a bit. Let's say that I give you instructions on how to go to the supermarket and buy some groceries and then put them away in the fridge when you get home. If you now want to buy groceries to make a meal immediately, are you going to need me to provide a whole new set of instructions? Of course not. It's only the last part that changes, i.e. what you do with the groceries once you get them home. The same goes here. What you do with the data once you've got it has no bearing on how you get the data in the first place. Getting data from a SerialPort is the same no matter what you intend to do with it. If you want to assign that data to a variable then go ahead and do so. Presumably you know how to assign something to a variable. How that's done doesn't change regardless of what the something is and where it came from.
