A    Device Mnemonics

This appendix identifies and defines the mnemonics that you use to attach any hardware or software device to your system. You specify the mnemonics with the MAKEDEV command to create the character or block special files that represent each of the devices. You also use the mnemonics to specify device special files for the loadable drivers described in the /etc/sysconfigtab configuration database file.

Table A-1 lists the mnemonics in six categories: generic, consoles, disks, tapes, terminals, and printers. The generic category lists the mnemonics of a general nature and includes memory, null, trace, and tty devices. The consoles category lists mnemonics for the system console devices that the Digital UNIX operating system uses. The disks, tapes, terminals, and printers categories identify the appropriate mnemonics for those devices.

The Description column in Table A-1 identifies the corresponding device name. It does not define the mnemonic's use. For detailed information on the use of each mnemonic in relation to the MAKEDEV command, the cfgmgr configuration manager daemon, and the system configuration file, use the man command. For example, enter the following command to display the reference page for the SCSI disk controller driver:

% man rz 

Where appropriate, the reference page defines the device's syntax as it should appear in the config file. For additional software device mnemonics that the MAKEDEV command uses, refer to the MAKEDEV(8) reference page.


Note

Table A-1 uses the convention of an * (asterisk) beside a mnemonic and a ? (question mark) beside a device name to indicate a variable number. The value of the variable number is dependent on the particular device.
