When the Server is in Run mode, the Suspend Protocol menu item is available. Suspend Protocol permits you to pause the operation of the Server without breaking the DDE links established by client applications. You might wish to do this to scroll back up the communication log display for trouble-shooting purposes. Suspend Protocol does not allow you to enter Configure mode or make any changes to the operational parameters of the Server, whereas the Stop command breaks the DDE links and allows configuration of the Server.

To take the Server off-line for additional configuration or diagnostics, click the Stop button on the Toolbar, or select Stop from the Server menu.

NOTE: Selecting the Stop command will attempt to stop the DDE Server, but if there are active DDE links with client applications, the Server displays a message that these links are present, and the Server cannot be stopped until you have closed any active links from client applications. Switch to any active client applications, close active links, then return to the Server and select Stop again.
