-This directory contains a telnetd server
-primary features:
-
-   + create a user shell pseudo-terminal task.
-
-This code has not been extensively tested.  It is provided as a tool
-for RTEMS users to open more shell tcp/ip pseudo-terminal.
-Suggestions and comments are appreciated.
-
-Read libmisc/shell for more information.
-
-NOTES:
-
-1.  OOB not yet implemented. Only a reduced negotiation is implemented.
-    
-2.  If you have tcp/ip initialied you can start telnetd daemon.
-    You need register pseudo-terminals driver into device drivers table.
-
-Enjoy it.

- *   WORK: fernando.ruiz at ctv.es
- *   HOME: correo at fernando-ruiz.com
- *
- * After start the net you can start this daemon.
- * It uses the previously inited pseudo-terminales (pty.c)
- * getting a new terminal with getpty(). This function
- * gives a terminal name passing a opened socket like parameter.
- *
- * With register_telnetd() you add a new command in the shell to start
- * this daemon interactively. (Login in /dev/console of course)
- *
- * Sorry but OOB is not still implemented. (This is the first version)
- *
- * Till Straumann <strauman at slac.stanford.edu>
- *  - made the 'shell' interface more generic, i.e. it is now
- *    possible to have 'telnetd' run an arbitrary 'shell'
- *    program.
