Welcome to A1vbcode Black Out. Ok you've used VB3 in the past but I'm assuming you have VB6 now? I would say you are going to need Microsoft Comm Control 6.0 - MSCOMM32.OCX to send and receive data. CDRIVE is our expert with this control so I would wait until he comes around?
I still use VB3 just for decompiling old apps.
