NTI SERIMUX SERIES CONSOLE SWITCH
User Terse mode
This mode is especially useful when the SERIMUX is directly controlled by external software from a serial console (as a user without administrative privileges), rather than being controlled by a user from a keyboard interface.
Entering short command strings performs functions similar to the user main menu commands. A [CR] – [LF] sequence ends every string. The commands are not echoed; the SERIMUX returns to the serial console a specific answer if the command is successfully accomplished or an error message otherwise.
Terse mode can be used only if the administrator configures a user port to enter into Terse mode at login. If a
