COURIER HIGH SPEED MODEMS
Data Mode Operations 4-13
Resetting the Modem
Z Software 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
E n 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 E
n 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 E
n 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.
F n 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.
