pad echo n

Sets the PAD echo mode – if echo is enabled then all data sent to the modem on its RS232 port by an external device is echoed back to that device.

n = 0	PAD echo mode: disabled
n = 1	PAD echo mode: enabled (default)

Examples:

Disable the PAD echo – characters received on the modem’s RS232 port will not be echoed to the connected device :
cmd pad echo 0
