1-1 1: Introduction The Lantronix MSS family of Device Servers allows you to network-enable a variety of serial devices that were not originally designed to be networked: personal computers, terminals, modems, industrial machinery, and more. Certain MSS models offer fiber optic Ethernet, PC card support for 802.
Introduction Command Line Editing 1-2 Please read this section carefully so you can understand the conventions used in the command descriptions. ◆ Commands are listed in alphabetical order. ◆ Some commands do not apply to all members of the MSS family, and are so noted.
Introduction Help 1-3 1.4 Help Context-sensitive help is available at any time. You may type Help by itself for overall help, Help <command> for help on a specific command, or a partial command line followed by a question mark for help on what is appropriate at that particular point.
2-1 2: Command Reference This chapter describes all commands that can be used with the MSS. The commands are listed in alphabetical order, excluding the Ports and Server parameters, which apply only to the MSS4. For example, Change Server Bootgateway is considered the same command as Change Bootgateway and is alphabetized according to the latter.
Command Reference Backward 2-2 2.1 Backward Moves the user to the previous session when entered in Local mode. See Also Change Backward Switch, page 2-14; Show Session, page 2-66. 2.2 Change 80211 Note: The Change 80211 Reset command must be entered after any 802.
