I want to connect two linux machines by their parallel ports, the cable is ready. Plz tell me how to write data to the port and read it at the other port.
For example, if i want to write 11001100 10101010 to the to the parallel port and read it at the other end. plz giv the C functions involved and their syntaxes. Thx.

I wonder why do you want to use parallel port (mostly for printers)? Why don't you consider using serial port(s)?
If you could use serial, you can find 'struct termios' and associated functions usefull.

There is also some old code that's probably still available for Linux called Parallel Line IP (PLIP) that I'm sure you could find more about through an Internet search, unless you really wanted to re-invent the wheel...

Some good info on the parallel port of course you can google for more.

Are you trying to network 2 PCs or talk to some device connected to the parallel port?
