VB2008 SeiralPort Communication With RS232?Jun 20, 2010
At the moment, I need to write a simple peice of software using VB.
I have a computer with VB2008, a RS232 interface; a electronic scale with RS232 interface; a cable with two female sides(this cable is file transfer cable, it enable data transfer between two computers according to the instruction)
My task is to connect the scale to the computer and the computer will keep track of the data sent from the scale.
how to get started? I'm new to VB and have no background in seiral communication, please give details.
My first question is: I have connected them together with the cable, how can I make sure they are really conected (able to communicate)? And can anybody give a peice of code to let me start building on that?
