Glenn... you are on your own. You need to learn enough about VB to correctly label and initialize the form objects.
If you do as I instructed, the form will work.
I have actually done your project for you. The code on both sides of the com port work. If there is anything left to do, or if for some reason the communications still do not happen then you must work it out yourself.
I wish you Good luck, but this will be my last post to you except perhaps say congratulations, if you send a post that says you completed the project and made it work.
