Linux Driver Development
I want to study the development of drivers on Linux. Very hardcore stuff.
I found a great book, or rather the ONLY book, on the topic here.
Does anyone know if there exist simple inexpensive hardware dummy devices to test input to and output from serial ports and parallel ports?
I have heard of something called breakout boards but was not really able to understand what they do. Would these be what I want?
How about dummy devices for USB or LAN?
How about some USB lamp? Should be cheap and you can still practice some simple techniques. (For me they are all complex though :-))

A breakout box is simply a small box, with D-Sub connectors on each side, so you can insert it between two serial devices. Usually it has switches or a jumpering system to allow you to connect the conductors of the two serial cables in arbitrary ways. They also usually have tri-color LEDs that can be used to see the states of the various signals in the RS-232 interface. 20 years ago every IT nerd had one of these beside his coffee cup; now I don't know where you'd buy one.
Are you planning to re-write the existing drivers for standard serial/parallel PC hardware, or are you going to use those devices as tools to exercise/monitor some other device for which you'll create a driver?
