Author: fernando.ruiz@ctv.es (correo@fernando-ruiz.com)
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 inited you can start telnetd daemon.
You need register pseudo-terminals driver into device drivers table.
16 ptyX termios device terminales are created into /dev/.
Calling rtems_initialize_telnetd() starts the daemon.
Enjoy it.
FUTURE:
