Message Server
The Message Server within the HP 86037B is automatically invoked by the
login to the test executive. After opening a window titled MsgCenter, its initial
action is to connect to socket 4444. When the connection is completed the
Message Server then awaits a read event on the socket.
When messages from the remote control program arrive at the Message Server
they are interpreted and appropriate action is taken.
In response to a STOP message, the logout function in the test executive is
called and the Message Server is shut down. Similarly, when a CANCEL or
ABORT message arrives, the appropriate test parameter variables are set
within the test executive.
When messages for running a test are received, built-in functions for creating
the list of tests to be performed are called, followed by the creation of the test
parameter collections and finally, the function to actually execute the test.
Following the execution of a test, the Message Server will await the reception
of another message.
Message Client
The message client on the remote machine may be any software that correctly
sends the above commands via socket 4444 to the message server on the
HP 86037B.
