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.
