Executes an echoback communications test between specified nodes.
Test data (command, response): For the command, up to 1,998 bytes of
data can be specified to be sent to a specified node. For the response, the
test data that was sent by the command is returned unchanged.
An error is generated if the data returned by the response is different from the
data that was sent by the command.
Reads for each node the results (number of receptions) of a BROADCAST
TEST DATA SEND command that has been sent to all nodes in a specified
network. (For details on the BROADCAST TEST RESULTS SEND command,
refer to 6-5-10 BROADCAST TEST DATA SEND.
Number of receptions (response): The number of times that broadcast test
data has been received at the command destination node from the time that
the last BROADCAST TEST RESULTS READ command was sent until this
one was sent is returned.
An error will be generated if that number of receptions differs from the number
of times that the BROADCAST TEST DATA SEND command was issued dur-
