Hello all,

I have a mobile phone sim card reader which is a USB-to-Serial port devices, however I only have the driver with me with no software application available. I would like to write a vb program to read and write the contact person name and phone to/from my pc. Any idea how would I retrieve the data stream from the port ?
After I installed the driver, I can find it under "Device Manager" -> "COM and LPT" (port 4)
Appreciate for any comment or related document.
