Good, I am developing a java client to connect to a Unix server via Telnet, it connects me well without problems, it accepts commands and everything, but at the time of printing the on-screen menu does not recognize the vt100 configuration to order the screen . Does anyone have any ideas? I'm using the commons-net library
Apache Commons Net does not implement the management and composition of screens using terminal control codes such as vt100 even if it allows you, by default, to negotiate said protocol.
You should interpret the control codes yourself, but implementing them is not trivial and you probably do not want to start the task from scratch.
I recommend that you take a look at the following Java applications that implement this protocol:
