Commands
In this manual, unless otherwise specified, any “key” stands for the ones on the PC keyboard.
The screen referred to is the PC monitor screen.
2-1 Command mode and Converse mode
The typical operating modes of this unit are the Command mode and the Converse mode.
It is necessary to use the command mode to set internal parameters in the EJ-41U. When the
unit is in the command mode, the “cmd:” prompt will appear on the screen. If “cmd:” does not
show up, press enter (or carriage return [CR]).
The converse mode enables the EJ-41U to transmit text as data. Use this mode for sending files
and/or text. Press the Ctrl and C keys together to return to the command mode.
