Description
The STB will execute a SendUserCommand command by sending the defined user
command to the user interface task.
This operation can take place whether command DisableUserEntry (0x13) is active or
not. The STB will respond to the user command as though a user button on the keypad
or remote control were pressed. Most commands require both a down and an up key
press.
The type Key Toggle will take 60 ms.
Note: There is a chance for command conflict if DisableUserEntry is not active,
particularly from stray IR remote control signals.
