ASTi Telestra Remote Control Interface User Guide (Version 1, Revision A)

List of Commands and Responses

The Telestra federate expects all command lines to be terminated with a <cr> character ( \n to

you C programmers). If two command lines come at once, they will be executed in order. A com-

mand will not be executed until the ﬁnal <cr> is received.

Commands are not case sensitive. Some data for the commands may be (for example, the fed ﬁle

name must be in the correct case). Where possible, data will not be case sensistive.

Telestra system replies that are of variable length (for example, when retrieving statistics or object

lists) will end with the line " ENDLIST<cr> ". This is indication to the host computer that no

more data is being sent.

If the interface receives a command it does not recognize, it will return " UNKNOWN COMMAND "

followed by the unrecognized command. If it receives a line of whitespace (followed by a <cr> ),

it will respond with a <cr> .

HELP

Either command returns a list of all the supported remote control interface commands.

JOIN <Federation Name>

This command directs the Telestra federate to join the federation with the name speciﬁed. If

no name is given, it will join the last federation name that was set. If the federate is already

joined to a federation, it will resign and attempt to join again. It will do this even if the federa-

tion name is unchanged. If no federation name has been set (either through the remote control

port or from the conﬁguration ﬁle), then the JOIN command will fail and respond " JOIN

<NONAMEGIVEN> FAIL ". The response to the JOIN command is either " JOIN Federa-

tionName OK ", " JOIN FederationName FAIL ", or " JOIN FederationName

FAIL BAD_FED_FILE ". The last response occurs if the federate could not get handles for

all of the class names and attribute names it requested from the RTI. The normal cause of this

is that the .fed ﬁle does not have the ASTi SOM information incorporated into it.

RESIGN

This command tells the federate to resign. The response will be " RESIGN OK " or " RESIGN

FAIL ". If the federate is not joined to a federation, no action is taken and the federate will

respond " RESIGN OK ".

SHUTDOWN

This command will instruct the Telestra system to do an orderly system shutdown. If the fed-

erate is currently joined to a federation, it will resign before shutting down. The Telestra

response to this command is " GOODBYE ", following by the connection being broken. The

shutdown will not complete until some time after the " GOODBYE " response is received. It is a

good practice to wait at least 60 seconds between receiving the " GOODBYE " and powering off

the Telestra system. Otherwise, the ﬁle system may be corrupted.
