Hi! A long time ago I got a parallel port scanner which only works under a proprietary operating system because the manufacturer only develops drivers for that os. I spent hours on searching a parallel port sniffer for that operating system so that I can understand how the communication between the device and the computer works. Unfortunately I didn't find a single parport sniffer. Then I sent some emails to the manufacturer, but they never answered my questions. Now I only see one chance to get the device work under linux: I want to write a driver that simply logs the traffic on the parallel port (the scanner works together with the computer via a virtual machine that uses the linux parport). What I want to do is to write a driver that implements all the system calls that the original parport driver implements. Each routine would only be a redirect to the original parport driver. Besides it should write all the traffic into a file. As I'm totally new to kernel development (I only read some books about it a year ago), I ask myself if it is possible to open a regular / device file in kernel mode. Sorry for my bad english.
