Use your COMM properties in VB, or a OCX for serial comm.
For event comm maybe you can adapt code from:

anyway if you are ging to do a real serious job don't use vb...
1. control and time response is not so deterministic
2. if you put the vb program in a "complex language system" (chinese for example) it will not work (or to make it works you have to do bad jobs a spend a lot of time)

bye
