-This directory contains a shell user extension
-primary features:
-
- + create a user shell terminal task.
-
-This code has not been extensively tested. It is provided as a tool
-for RTEMS users to open more shell terminal.
-Suggestions and comments are appreciated.
-
-NOTES:
-
-1. printf() & getchar() works but you can't use
- 0,1,2 like fildes. You need to use fileno(stdin),fileno(stdout),...
-
-2. You only need a termios dev to start a new session, add your new commands
- and enjoy it.
-
-3. Telnetd daemon uses this (browse libnetworking/rtems_telnetd)
- Enjoy it.
-
-FUTURE:
-
-1. Adding new commands in cmds.c to give file manegement to shell.
