Used to request or yield Active status. The 'Px' argument specifies the port that
XDS activity will be set to, i.e. P1. Port P3 can set the Active status of any port.
The other ports can only request active status for itself and so does not need to
enter the Px parameter. Active status can only be obtained if the port has been
authorized in the Permission List.
Only one port can be active for each Data Type at a time. If another port is
already active the E1 error message will be returned. If the command is entered
with the override parameter O, the port entering the command will become
active in place of the previous active port.
Creates an XDS packet and loads it into the XDS queue. The Legalizer will
begin inserting the packet immediately.
 Packet sets the XDS Class and Type of the packet that will be created. If a
new packet is loaded with the same Packet ID as an existing packet in the
queue, the pre-existing packet will be deleted; if the new packet is a
Program Name or Program ID packet, all program-specific packets will be
deleted from the queue. A packet loaded into the Legalizer with the Load
XDS Packet command has local priority; in output signals, it will replace
all upstream packets of the same Class and Type.
The Packet parameter should be entered as Class immediately followed by
Type in the way shown in the table below. Leading zeroes may be omitted.
The Class and Type of a few of the most commonly used XDS packets are
shown in the following table; for a complete list refer to CEA-608B.

Current Program Length
Current Program Name
Current Program Rating
 Duration sets the transmission duration of the newly created packet. When
a packet's duration period expires, it will be deleted from the XDS queue.
A duration setting of –1 will cause the packet to be inserted until it is
deleted by a future command. An integer setting (i.e. 100) will be
interpreted as the number of times to output the packet before deleting it.
An Elapsed Time setting (i.e. 00.45.00), will cause the packet to be inserted
for that length of time, beginning when the command is entered, and then
deleted.
