Hi Steve,
How the petrol pump pass signal to a PC, with a series port or parallel
port? In VB.NET, we have a control named "serialPort" that can monitor the
communication on serial port resource. And here are some articles on this:

You may first consult the vendor of the petrol pump, if it support be
communicate with series port. If so, you may use this control for it.
Sincerely,
Luke Zhang
