I want to test both the LAN port and the DB9 Com1 port of the same laptop using purely VB.Net tools. If I were to get a RJ45 to DB9 adapter, how could I open a communication channel between the two?

You can't connect them directly together, they are not electrically compatible, simply will not work together.

Is there a way to loop back the RJ45 port similar to the way a RS232 port is looped back for testing? In other words, can I somehow send data and receive it back on the same LAN port of the same laptop? As I said above I need a pure .Net approach.

Thanks for the help.

Here's one http://www.stayonline.com/detail.aspx?ID=12156 .   I don't know if it will work with the NIC drivers though since they are expecting another device to be connected to the cable.  Testing is normally done at a low level.  "a pure .Net approach" uses the Windows drivers and will be limited by the capabilities of the drivers.
