NAME

mvme332xt − create character device files

SYNOPSIS

/sbin/auto-device/mvme332xt [−v]

DESCRIPTION

The mvme332xt command creates character device files in /dev/port and /dev/printer.  The mvme332xt command created character device files in /dev/port for eight asynchronous RS-232 ports and in /dev/printer for one parallel printer port for every mvme332xt board in the kernel’s Equip Device Table (EDT).  The entries in /dev/port are the controller specific namings of the above mentioned ports.  Their format is /dev/port/m332_cXdY where X is the controller number and Y is the port number.  /dev/printer contains the parallel printer controller specific naming /dev/printer/m332_cXd8 where X is the controller number.  A port is named sn, where s is the board number and n is a number from 0 to 8.  Board numbers start at 0 and increment by 1. 

When mvme332xt is invoked, it does the following:

removes any /dev/port and /dev/printer controller specific device files for boards that no longer exist

makes new /dev/port and /dev/printer printer files for the mvme332xt boards as needed

The mvme332xt command is invoked only upon system installation or when reconfiguration and reboot of the system prompts a new kernel to be created.  The −v option sets the output to verbose. 

Devices in /dev/term are created by the makedev(1M) program. 

Any devices, such as a printer or a modem, that are added to a mvme332xt board should link the names that are to be used for the devices to the corresponding tty device files that were created [see ln(1)].  The command can be used only by the super-user. 

EXAMPLE

A parallel printer is added to a mvme332xt board that is board number 1.  The corresponding slot is /dev/printer/m332_c0d8.  The user should use ln to link an appropriate name such as lp1 to the tty device file. 

ln /dev/printer/m332_c0d8 /dev/lp1
