6.2.2 Implementing Java applet
Program source for terminal applet is located in “the HelloDevice Install folder\Src\SerialDemo\java” folder.
The source code is from public domain free source, “telnet java applet”. We modified the code so that it may
work with the HelloDevice. Further information on “telnet java applet” can be found in the folder of
“1300_telnet_documentation” of the HelloDevice install CDROM.
