9–2 • Appendix A. Software Interface for LAN

TES9 Software User Manual (Iss. 04)

Overview

The LAN encoder makes use of the TCP/IP protocol to transfer data. Better error free data 
transmission is ensured since the encoder uses TCP packets as opposed to UDP packets. This 
eliminates the possibility of lost data during transmission.

The basic steps to establish a connection and send data to the encoder using the winsock static 
library are: 

1.

Initialize winsock using the 

WSAStartup

 command.

2.

Get the name of the sending computer using 

gethostname 

command.

3.

Get the IP address of the sending computer using the 

gethostbyname

 command.

4.

Copy the IP address part of the HOSTENT structure to another structure of type 
IN_ADDR.

5.

Create a socket for making a connection using 

socket

 command.

6.

In order to improve efficiency and make it possible to run multiple copies at once, it is 
necessary to use the non-blocking commands available in the winsock static library. This 
makes use of the Microsoft® Windows® message processing loop. Do this by issuing 
the 

WSAAsyncSelect

 command.

7.

Bind the socket created in the step above to the TCP/IP protocol and accept       
connections for any port number using the 

bind

 command.

8.

Fill structure SOCKADDR_IN with the destination information. 

9.

Establish a connection using the 

connect

 command.

10.

When connection has been established the W 100 message is sent to the 
Microsoft® Windows® message loop.

11.

After all data transmission is finished, the sockets must be shut down using the 
following commands: 

shutdown

, 

closesocket

, 

WSACleanup 

commands.
