Hey,

My boss put me in charge of getting this pin pad device to work with our software.

We have it plugging into the usb port with a converter cable that converts it to a rs232 port. This converter cable uses the pl2303 driver to aid with this.

I am new to drivers, particularly on the windows OS. My question is how do I use this driver to communicate with the device?

I'm trying to read into it but am being overloaded by information and I think I could use some help. I was reading something about using the win32 api and using create file to get a handle? I found this to be quite confusing and am having trouble finding examples of how to use this handle. Isn't there just some standard I/O library I can use to communicate? Please help!

Here's some info on the device:
