devs File

The devs file defines the various devices in the system.

Description

This file, located on the dm account, has two data levels:

For UNIX: Items in this file may be added or removed with the dev-make or dev-remov TCL commands.

For Windows: Not supported.

The item-IDs in this file are the entity-IDs, which are composed of a one letter code p for D3 ports, s for serial device, e for Ethernet, and so on), followed by the entity number in decimal (the D3 port number, the serial device number, the TCP/IP connection-ID, and so on).

Both data levels can be examined using AQL or the Update Processor. The structure of an item in these files is described in the include dm,bp,includes qcb.inc.

Example(s)

Examines the characteristics of serial device 12, opens the Update Processor, and allows changing the initial setting of the serial device. Filing this item does not actually change the setting. It is changed the next time the reset-async command is run (normally at boot time) or by running the reset-async s12 command.

u devs,init s12

Examines the characteristics of D3 port 0. The only element than can be changed is the tandem flag, which controls whether or not tandem is allowed on port 0, and whether the target process should be notified about the tandem on/off.

u devs p0

Show the current status of all serial ports.
