TCHMllpServer Component
Properties Methods Events

This object implements a Lower Layer Protocol (LLP) TCP/IP server that listens for connections from clients.

Unit
CHMnet

Declaration
TCHMllpServer = class(TComponent)

Description

Most of the network events that are raised provide a ICHMllpConnection parameter, which gives methods to interact with the client connection that the event is associated with.

See http://www.interfaceware.com/manual/network_components.html for more information.


Properties
Client Representation of the collection of remote Clients that are connected to this server.
HeaderBlock The characters that precede a message in a stream.

Port The port on which we are listening, set by the StartListen method.
