attempt at loopback only network test

[Correo Fernando-ruiz (E-mail)]

This is the same case that the rtems_telnetd().

The server accept new conections. Keep the opened socket giving this
fileno() like
stdin,stdout and stderr at the new shell until the close of socket
in any side.

Seeing the rtems_telnetd() implementation this case you can see a real rtems
tcp/ip implementation.

In the case of the server rejects the MAX USERS the server telnetd() works
like you want.
Listen, accept(), open, write close.
More?.

My source was a QUE Book Linux programing with examples.
Too easy but too direct.
After a Stevens's book Bible.
