Commons-Net

Bom dia!!

Senhores(as) eu preciso de uma grande ajuda. Tenho que desenvolver uma aplicação que deverá se conectar em uns equipamentos da nossa rede via Telnet, e após conectado deverei executar três comandos(show system, show worp, show wif). Esses comandos após executados trarão informações dos equipamentos(stringão mesmo).
A minha dificuldade está sendo a seguinte, eu tenho uma lista de equipamentos e a mesma tarefa(comandos) será executada para cada um deles, e existe a necessidade automatizar esse processo, não pode ter intervenção humana.

Mas quando eu dou um connect ele para, aguardando a senha havendo a necessidade de ‘intervenção’

TelnetClient tc = new TelnetClient();
tc.connect(remoteip, remoteport);
//1º PEDE SENHA --aqui queria deixar automatico
//2º Após logado, executar o show system
//3º Após logado, executar o show worp
//3º Após logado, executar o show wif

Estou usando"commons-net", e sinceramente estou levando um surra!
agradeço por qualquer ajuda
