External Control Commands
Explanation:
This command is used to enable or disable the IR control port and is equivalent to
the IR enable and disable commands available through the Firefly menu system or
the handheld IR remote. No channel number is ever specified as this command is
always global. A value of 0 for x will enable IR control while a value of 1 will
disable IR control. Any other value will be considered an error and will return the
error code NAK without changing the state of the IR control port.
Examples:
0KL
Enables IR control port. If the IR control port was already enabled at the time this
command was received, no change is made.
1KL
Disables IR control port. If the IR control port was already disabled at the time
this command was received, no change is made.
Display Control (DS)
Command:
Turns the on screen status display on or off for the specified channel(s) within the
Firefly.
Format:
xDS<CR>
Response:
R<CR>
Explanation:
This command is used to call up a graphic overlay onto a specified channel(s).
The graphic overlay will be a subset of the status display shown during IR remote
control player control mode. All elements of that overlay except the border box
around the edge of the picture are included. A value of 0 for x will turn on the
graphic overlay while a value of 1 will turn off the graphic overlay. Any other
value is considered invalid and will return an error code of NAK without
changing the state of the graphic overlay.
Note that it is not necessary for the Firefly to maintain the state of this overlay
when IR player control inputs are received after a serial command to display the
overlay. In other words, if a serial command turns on the display and then the
handheld remote is used to enter manual player control, the player control rules
for overlay will take over and it is not necessary to restore the overlay to its
previous state when player control mode is exited.
