Appendix A: Command Reference
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 Line Settings (Serial) (on page 48) 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

No flow control
Note: The latest firmware release, version 1.1.0.2R10, has a known issue for
boot to CLI in that it defaults to hardware flow control, thus it requires CTS to be
asserted.
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.
