Hi,
Unfortunately we are unlikely to have the bandwidth to put together any additional example more specific to your exact requirement, however the INETD already has a 'Chargen' server thread, which illustrates how to generate characters, and transmit them over ethernet.
Similarly, the Echo thread not only demonstrates how to receive input over ethernet, but also how to transmit a response to that input (it just so happens that it's a very basic echo). The basic foundations are there for generating and transmitting char data over ethernet, in order to send your 'menu' over ethernet, as are the foundations for allowing an input to be received (e.g. selecting which test to run by typing a number, or whatever).
If you have any specific questions or issues along the way, please let us know.
Regards,
Craig.
