Introduction¶

Many embedded applications benefit from communicating with a PC. However, not all boards have a USB or an ethernet port.

On the other sides, most embedded applications have a serial port!

So, instead of just sending simple serial messages to a terminal program on your PC, we would like to establish a network connection with the PC. This means that we can communicate to the browser on the PC.

The hardest part of doing this is to create a Dial Up Network (DUN) adapter in Windows.

This is done in two steps - First, you "install" a new "modem". In our case, you are really telling Windows that one of your existing serial ports is actually a "modem". Secondly, using the Network and Sharing interface, you create a new "connection to the internet".

All this is decribed in detail on the home page, but this page adds a nice touch - instead of choosing Communications Cable Between Two Computers choose I have a disk and present this file: /media/uploads/nixnax/ppp-blinky.inf

As you will see in the last line of the file, you will get a cool new modem named mbed PPP-Blinky over serial port instead of Communications Cable Between Two Computers
