Annoying VB Problem

I've been asked to make a program for my physics/chem teacher that involves sending info
over a serial port. My problem is that I have the program set up to catch the info he wants but
i need to know how to send the return keystroke after the user data so it knows it's done. I
don't know how to use comm controls in c/c++ so I'm doing this in VB for now because I have
to get it started, mahor project and all. If you know how to do this I'd be very grateful, or if you know a better way to do it, like in c/c++ if I can find a tutorial on using comm ports with it.
Thanks in advance.
