logical addresses currently installed in the mainframe. If the Command Module
is not the resource manager, it only returns the logical addresses of the devices
in its servant area.

values which will be returned by VXI:CONF:DLAD?.

Use each of the logical addresses returned by VXI:CONF:DLAD? with
VXI:CONF:DLIS? to determine the types of devices installed.

VXI:CONF:DEVICELAD? is also accepted.

This command has been retained for compatibility with existing
programs. For new programs you should use the VXI:CONF:LADD?
