Displays information about devices. Format SHOW DEVICE device-name:
1 – Parameter
device-name: The name of the device whose characteristics are to be displayed. The device name has the form ddcu, where: dd is the device code-for example, LP. (The driver name corresponds to the device code; in this case, the driver name would be SYS$LPDRIVER.) c is the controller designation A through Z; unless UCM specifies a different letter, all USB devices are A. u is the unit number (0 through 9999.) OpenVMS device names are made up of the two-character device code, followed by the controller designation, the unit number (which can be 1 to 4 characters long), and, finally, a colon (:).
2 – Display Qualifiers
2.1 /BRIEF
/BRIEF (default) Displays summary information for each device.
2.2 /FULL
Displays complete information for each device.
3 – Selection Qualifiers
3.1 /ALL
/ALL (default) Displays all device entries, including those that the /CONFIGURED, /GENERIC, /PERMANENT, /PHYSICAL, and /UNCONFIGURED qualifiers display.
3.2 /CONFIGURED
Displays all the devices connected to the bus that have been configured successfully.
3.3 /GENERIC
Displays the devices that are on the generic device list.
3.4 /PERMANENT
Displays the devices for which the system automatically loads device drivers if the devices are plugged in.
3.5 /PHYSICAL
Displays the devices that are connected to the bus even if drivers for these devices are not loaded.
3.6 /UNCONFIGURED
Displays devices that are attached to the bus and that have drivers, but that do not have entries in the permanent list. (These are also known as tentative devices.) You must execute an ADD DEVICE command to make these devices part of the permanent list. Once the drivers have been added, the device is automatically configured the next time it is plugged in.
