The ZAURA RF Wireless Module Shell can be configured to echo char-
acters received on UART0 Rx to UART0 Tx. This echo configuration
allows the operator of the console terminal program to see the characters
he or she is typing in the terminal window. However, the terminal pro-
gram will also typically include a
local echo option in which the termi-
nal program automatically displays characters as they are entered in the
terminal window. Configuring both the PC terminal program and the
ZAURA RF Wireless node to echo UART data will result in two charac-
ters being displayed for every entered character, while disabling
echo on
both sides means that the operator will be typing blind.
The default ZAURA RF Wireless Module UART echo setting is con-
trolled by the
ZAURA_RF_UartEcho configuration variable. The value of
this variable can be programmatically modified at run time; it can also be
modified by using the
uecho console command. If the uecho command
is issued without any parameters, it will display the current UART echo
state. To enable UART echo, issue the command
uecho on . To disable
UART echo, issue the command uecho off .
