Custom Commands


This is currently just a brief overview to feed the search engine. See each command’s usage info and where applicable corresponding V2 manual entries on details.

  • V3 commands need to be in lower case.
  • When accessing via USB terminal, first issue enable (login).
  • V3 commands are similar to V2 commands, just structured slightly different.
  • Try help, ? and xrt ?. Twizy commands are subcommands of xrt.
  • TAB only works via USB / SSH. Shortcuts can be used generally, e.g. mo t instead of module tasks.
  • A usage info is shown if a command syntax is wrong or incomplete.
