Configuration Using Serial Port
Serial Command Mode
The serial port can be configured to operate in command mode permanently or to be triggered
under specified conditions. See the line <line> Level command description for more
information.
Boot to CLI
Regardless of the configured settings, the CLI can be accessed via Line 1 using fixed settings and
the "back door" procedure. The original configured line settings will be restored once the user exits
the "back door" CLI, unless any Line 1 settings are changed within the "back door" CLI.
To configure the Lantronix xPico Wi-Fi embedded device server locally using a serial port:
Note: The xPico Wi-Fi embedded device server requires that flow control be used on the
serial port to ensure the best performance when importing XML.
1. Connect a terminal or a PC running a terminal emulation program to one of the xPico Wi-Fi
embedded device server's serial ports.
2. Configure the terminal to the following settings:
9600 baud
8-bit
No parity
1 stop bit
Flow control enabled
Note: Lantronix recommends using hardware flow control.
3. Power off the device.
4. Get into the serial backdoor as follows:
a. While asserting the defaults signal,
b. Reset the device while sending X, Y, or Z characters.
c. When the incoming characters are recognized, a prompt in the following form will be seen:
xPicoWifi <MAC ADDRESS>
Note: It is important to release the defaults signal as soon as possible after the
prompt is seen; continuing to hold it down may result in a reset to factory defaults.
OR
a. While asserting the defaults signal,
b. Reset the device while sending ! character until it is echoed back.
c. Then release the defaults line, and enter xyz.
