[amol]

hi

 i am connecting pathology laboratory instruments to pc using vb6. Till now i was connecting using serial port. But now a days lab instruments are also coming with usb port,lan port for communication. if i want to connect them to my pc's usb or lan port , how to programme with it. How to use oncomm event? Will it work with normal  usb - usb cable?

The drivers for your lab instruments should create a virtual serial port for the USB connection. In this case you can use your vb6 app too.

Thanks. But will it work with normal usb-usb cable or some specialised cable. What about lan port ? Do I need to switch to winsock

If you'll use the lan port, then you'll need a description of a data exchange protocol. It may be simple than a pure USB connection.
