Please search MSDN as I am sure there are code snippets on there for COM
port, but you need to know which pin takes what to be able to control it
perfectly

Dont know if it is what you are looking for, but this might be useful

Hi there,

You can use the Microsoft MSComm32 ActiveX control(VB6 and VB .net).
You can find more information on internet about how to use this
control.
