the pop-up menu. If you do not GCFSTOP, the server will
continue to transmit to a client that is no longer listening. You
should ensure that the server replies with a GCFACKN message If
an acknowledgement does not appear in the Control pane, repeat

the GCFSTOP command.

The steps above can be repeated as many times as necessary to pull data

from several servers, but care should be taken to GCFSTOP each one
before terminating the application.

My Server

Scream!'s server can transmit blocks of data acquired from local

instruments over the network via UDP. The list of clients that are
currently being sent data is shown in the Clients table at the top of the

window. Block-by-block details of the data being transmitted are
indicated in the Block Tx pane. Other server operations are logged by
messages in the Control pane to its right.

Scream! can either push data to a network device or wait for it to be
pulled off it. The server can behave in different ways for different clients.

You can see which clients are using which method by looking in the

Timeout column: pushed clients have a timeout value of 0, whilst
pulling clients have some other timeout value (after which, if nothing is

heard from them, they will be removed from the list.)
