SUPPORTED DEVICE FEATURES

The following sections describe the OPOS features that are not supported or partially supported
for each device class. The restrictions are based on the functionality of the supported MagTek
devices. In some cases, features not supported by the device (e.g., multiple windows in the Line
Display) can be implemented by OMTD in software at a later time.

Common Features

Common Properties

Property Name

Comments

CapPowerReporting

This property returns OPOS_PR_NONE for all devices because
no MagTek devices have power reporting capabilities.

Claimed

All devices must be claimed before access will be granted by the
control.

PowerNotify

This property is initialized to OPOS_PN_DISABLED and the
control will fail any attempts to enable this property because it is
not supported by any devices.

PowerState

This property will always return OPOS_PS_UNKNOWN because
CapPowerReporting is OPOS_PR_NONE.

Common Methods

Method Name

Comments

CheckHealth

Only OPOS_CH_INTERNAL is supported by the SO. All other
levels are mapped to OPOS_CH_INTERNAL.

At this time, no commands have been defined for this method.
See the Discretionary Features section later in this document for
more details.

Common Events

Event Name

Comments

DirectIOEvent

Used only if asynchronous DirectIO method is supported.

OutputCompleteEvent

This event is not used because all output is performed
synchronously for the device classes supported by OMTD.

StatusUpdateEvent

This event is not used because the power state reporting
capability is not supported and no status update events are
defined for the device classes supported by OMTD.
