* monitor/mon-prmisc.c: Correct print line. * shell/Makefile.am: Added new file telnetd.c. * shell/telnetd.c, shell/telnetd.h, shell/pty.c: New files. * shell/shell.c, shell/cmds.c, shell/shell.h: Numerous improvments: - The shell_init has a new parameter 'forever' because in /dev/console you need that this process runs forever but in tcp/ip not. (respawn?) - A new task for every session opened trought tcp/ip telnet client. (the chargen,daytime and more are possible of implementation but I ask me if they are necesary) - Exit from the session delete the task and when the client fails too. - More cmds have been implemented. (very reduced version of these) umask, chmod, id, whoami, rm, cat, ... - A reduced line edit has been implemented. Ctrl-C abort the input, Ctrl-d in the first position gives EOF (logout). '\b' and DEL makes the rubout operation. I think that readline() for every session spents a lot of resources.
