MRRECHDR Monitor Record Header
NAME - MRMTRDEV
DESCRIPTIVE NAME - Monitor Sample Configuration Record
Domain 1 - Monitor Domain
Record 6 - Device Configuration Data
DESCRIPTION - Describes the configuration of a real device. A
separate record is generated for each real device
defined to the system.
NOTES:
- If the device is offline (see MTRDEV_RDEVOFFL),
only the following fields will be valid:
MTRDEV_MRHDR
MTRDEV_RDEVTYPE
MTRDEV_RDEVCLAS
MTRDEV_RDEVDEV
MTRDEV_RDEVSHAR
MTRDEV_RDEVSER
