WiFI232: Implementing a full tcp/ip stack over WiFI232 interface using pppd

This video demonstrates a proof of concept of how to implement a full tcp/ip stack on an old school Pentium 1 233mhz mmx machine running RedHat 6.2, by connecting the machine over serial port to a Debian virtual machine using the awesome WiFI232 interface. You can find more information on the WiFI232 here: http://biosrhythm.com/?page_id=1453 The main idea is that: a) you establish a telnet connection to a remote linux machine using WiFI232 and Minicom b) get root privileges on the terminal and run pppd c) detach from minicom (with ctrl+a q) and run pppd on your local machine After doing this, a tcp/ip link is created between the two machines, so you can connect your computer to the internet as if you would back in the 90s, at 19200 baud rate! :D As you can see in the video, there are some snags with packet loss, though I believe those are caused by the small MTU. Anyway, I hope this proof of concept can help others!
