NAME
mknod - build special file
SYNOPSIS
/etc/mknod name [ c ] [ b ] major minor
DESCRIPTION
Mknod makes a directory entry and corresponding i-node for a
special file. The first argument is the name of the entry.
The second is b if the special file is block-type (disks,
tape) or c if it is character-type (other devices). The
last two arguments are numbers specifying the major device
type and the minor device (e.g. unit, drive, or line
number).
The assignment of major device numbers is specific to each
system. For reference, here are the numbers for the MH 2C-
644 machine. Do not believe them too much.
