386 Module - eFR
In a TCP client/server connection, a TCP Server listens on a specific port.
A client can reside on the same system or on another system, and make a
socket connection by specifying the address and the port the server listens
to. The following figure illustrates that the server listens on port 3102.

TCP client/server connection
If connection is successful, a connection is established between the
client and the server. In a NETSTAT command window, a line appears
illustrating that a TCP connection is found on port 3102 with the state
ESTABLISHED.
Figure 128
NETSTAT command window
The previous figure shows the client address and port in the third column,
10.1289.65.159:4817. In many environments the client is not bound to
a fixed port, and receives a random assigned port number, for example
4817.
The capability of eFR monitoring client connections of NETSTAT is
oriented towards application environments, with a persistent socket
connection. For example, DECT Messenger is an example of a software
suite based upon client/server architecture, where the majority of client
modules must be connected permanently with predefined ports on the
server. Typically you must monitor the TCP clients (eDMSAPI, eCSTA,
eSMS, eCAP
) modules connected to eKERNEL on the configured ports.
Sample e-mail
A sample e-mail is shown in the following figure.
