    Hi Babu

    You Could Try to use the GetDeviceCaps API

    Public Declare Function GetDeviceCaps Lib "gdi32" Alias "GetDeviceCaps" (ByVal hdc As Long, ByVal nIndex As Long) As Long

    You will need to pass the device context Handle and the constant. If you have the book by Dan Apple man it will help you immensely with Win APIs

    Regards
    Vikram

    Windows does not allow Applications to read/write directly to hardware ports. You may have to implement a VxD and an application or use a tool like DriverAgent from Numega.
