Aux Data - The Aux Data device is defined to allow for async data streams to
be carried within the transport stream and their raw payload output on an IRD
serial port. The PID of these streams may or may not be assigned to a program
number within a PMT. To recover the data, the IRD need only be given the PID
and baud rate. The range of legal PIDs is established by the ISO 13818 stan-
dard as 20 to 1ffe (hex). This may be performed either by COMPEL com-
mand or by the local user (if local control is enabled).
COMPEL - This device is defined to allow for input of the COMPEL control
stream (for testing only). There is no output.
PRINTER OUTPUT - This is an output-only device. For the Printer device,
there are three legal types: COMPEL-requested Reports, COMPEL E-mail,
and Raw COMPEL (binary) Data. The first output type are IRD status reports
identical to those that the local user may request. These are always available
for the Printer device. The second output type must be enabled by a non-vola-
tile control. The last type, Raw COMPEL, must also be enabled by a non-vola-
tile control (actually a factory setting that can only be modified with debug
access). It is exclusive of the other outputs (the others are not allowed if dump-
ing Raw COMPEL). For this type, the COMPEL data stream, while being pro-
cessed normally by the IRD host processor, is also output as-is to the Printer
device. This data is binary and includes non-printing characters.
