5.4. Remote Control Interface Commands and Responses
The Target federate expects all command lines to be terminated with a newline character (“
\n
”
for those who are C programmers). If two command lines come at once, they will be executed in
order.
A command will not be executed until the final newline (
\n
) is received.
Commands are not case-sensitive. However, some data for the commands may be case-sensitive
(for example, the fed file name must be in the correct case).
The Target replies are of variable length. This is an indication to the host computer that no
additional data will be sent.
If the interface receives a command that it does not recognize, it will simply ignore the new code.
If it receives a line of white space (followed by a newline character), it will respond with a
newline character.
ACTIVITY
This command returns activity counters from the Target. If accessing the remote control inter-
face through the host emulator utility on the Target, this command may be initiated by simply
pressing the <ENTER> key. See the sample output below:
life count: 0x41
<Attribute Updates>
rx: 0x6 | tx: 0xc | ignored: 0x0
<Interactions>
Audio | rx : 0x0 | tx : 0x0
TDL | rx : 0x0 | tx : 0x0
Attach | rx 0x0
<Objects>
Transmitters | local : 0x2 | rti : 0x1
Entities | local : 0x0 | attached
: 0x0
ENDLIST
The
life count
increments once a second while the entity is joined to a federation. The
count is a general indicator of federate health.
Attribute Updates
report the cumulative number of attribute updates sent and received
by the federate. The
ignored
is the number of updates received but ignored. This happens
when the federate receives an update for an entity object to which none of its radios are
attached. The attributes, which are defined in the ASTi SOM, include radio object parameters
such as power, world location, and frequency. An attribute update occurs whenever one of
these fields change.
Interactions
is the number of interactions sent and received. The interaction counters are
organized by interaction type. The
Audio
counters increment as the federate sends or
receives audio packets. The
TDL
counter increments as the federate sends or receives data
messages. The ASTi SOM versions 3.1 and higher define a data message interaction to imple-
ment tactical data link simulations in HLA.
