[TELNET commands for ADSL router ?]

Hi ,

i connected to my ADSL router via TELNET and want to configure it by TELNET .

While connected i request HELP and show these commands :

BCM96338 ADSL Router

(none) login: admin

Password:

BusyBox v1.00 (2005.04.12-18:11+0000) Built-in shell (msh)

Enter 'help' for a list of built-in commands.

# help

Built-in commands:

-------------------

. : break cd continue eval exec exit export help login newgrp

read readonly set shift times trap umask wait [ busybox cat dmesg

echo expr false fdefault ftpget ifconfig init insmod kill klogd

ledctrl linuxrc logger login logread mkdir mount msh ping ps

pwd reboot rm rmmod route sendarp sh sysinfo syslogd test tftpd

true tty vconfig

NOW , How i can config it ( for example NAT , FIREWALL , ... ) with TELNET commands ??
