Return Response

NACK_FCNOK : Failure – No User Command available since last request
Return Value
0x0000
: Success
Non-Zero
: Failure – No User Command available since last request
Description
The STB will execute a GetUserCommand command by providing the remote control
or front panel key presses via the Return Data Stream.
The DisableUserEntry command will be called prior to calling the GetUserCommand
command.
If a user command has transpired since the last GetUserCommand request, the user
command Type, Device, and Contents are placed in the return data stream. If a user
command has not been made since the last request, the NACK_FCNOK is returned
instead.
The GetUserCommand is used to identify the type, device and key. For example, if
the user pressed and released the Select (0xC3) key then one GetUserCommand is
required. The GetUserCommand provides a Type of 0x00 (Key Toggle), Device of
0x01 (Remote) and Key of 0xC3 (Select key). On the other hand, if the user pressed
the Select (0xC3) key, held it so that the remote repeats the command, and then
released it on the remote control, two (2) GetUserCommands are required. The first
GetUserCommand provides a Type of 0x01 (Key Down), Device of 0x01 (Remote)
and Key of 0xC3 (Select key). The second GetUserCommand provides a Type of 0x03
(Key Up), Device of 0x01 (Remote) and Key of 0xC3 (Select).
