Networking – Telnet router commands

I have an actiontec xdsl router (c1000a) that I am telnetting to but I can't get a list of commands for it. The only one I've found so far is arp. I haven't found a list of common router commands on google either. I want to see what my options are and see if I can save a boot up script.
Edit: the command list:
