COURIER HIGH SPEED MODEMS

Resetting the Modem

ZSoftware reset to NVRAM settings when DIP switch 10 is OFF (factory setting). If DIP switch 10 is OFF, the modem resets to the &F0 configuration template, with no flow control.

NOTE: Use the ATZ command also if you've changed the position of DIP switches 1−7 or 9 while the modem is on, so that the modem can read the new setting. The only other way to initiate a new setting for switches 1−7 and 9 is to turn the modem off and on again.

	CONFIGURATION
	Echo/Speaker
En	Command mode local echo. Enables/disables the display of
	your typed commands. If double characters appear on the
	screen, both the modem's local echo and your software's local
	echo are on.
	The Courier is shipped with DIP switch 4 OFF, enabling local
	echo. The En command controls the local echo for a current
	session, independently of the switch setting. At power-on and
	reset, the modem operates according to the DIP switch setting.
	The En command is not stored in nonvolatile memory as a
	power-on/reset default.
	E0 Command mode echo OFF. The modem does not
	display keyboard commands.
	E1 Command mode echo ON.
Fn	Online local echo. This command causes the modem to display
	a copy of the data it is transmitting to another system. Many
	systems, however, return a copy of received data, which is
	called a remote echo. If the modem's online echo is ON and
	there is also remote echoing, double characters appear on the
	screen.
