Linux device drivers...

[Jerry Feldman]

First, the files in the /dev/ directory are usually device special files and 
rarely are there normal files. When you do an ls -l, the first character 
before the permissions says whether it is a character or block device. 
In the following, ptyp0 is a character device with a major number of 7, 
and a minor number of 0. 
crw-rw-rw-   1 root     system     7,      0 Oct 22 14:48 ptyp0
Each driver is identified by a major number, and the device is generally 
the minor number, but that actually depends on the driver. Floppy names 
are normally set up as something like /dev/fd01440. There is a whole 
bunch of them. I don't have a linux system that I can log into from here.
