5.2.1 When the HelloDevice is TCP Server with a static IP address
The sample program enables the user to connect to the HelloDevice and send strings to the
HelloDevice, when the HelloDevice has been set as TCP server mode. The only difference from the
previous section is that we use the sample program for TCP/IP terminal program instead of TeraTerm
Pro. In this section, we will describe how to establish the connection and check data communication.
1) Connect serial ports of HelloDevice and the PC with the serial cable.
2) Launch serial terminal program such as TeraTerm Pro.
3) Open “Server.dsw” file in the “Server” folder and “Build” and “Run” the program.
4) Enter the IP address of the HelloDevice.
Figure 5.6 is a sample when the IP address of HelloDevice is 192.168.1.15.

5) Enter the Character string and press [Enter].
The character string you entered will be displayed on the serial terminal program of the PC.
