ABL looks for events to execute in the context of input-blocking or event-processing statements. During this processing if the AVM detects that data is available on a socket or that the remote end closed its socket or it detects that a client has connected to a port that the server has enabled connections to, a socket event is generated.
There are only two socket events, the READ-RESPONSE event, which applies only to socket objects, and the CONNECT event which applies only to server socket objects.
