On the ewonsupport server, you have access to a simple telnet server that allows you to practice the BASIC Scripting or Java Programming on eWON Flexy.
Indeed, BASIC Scripting allows you to develop your own custom protocol to connect this server and get random values.
In Java, you can even go further by developing your own IO Server. Here
you can find a BASIC script example.
The telnet protocol used is very simple :
You have to connect the server on the port 23.
You have first to send the command "hello".
You have then to send the command "value" to get a random value from the server. (you do it as many times you want)
Finally, the command "goodbye" can be sent to close the connection.
