Command Line Interface
To reset a lost or forgotten operator username/password, use F100 P and F100 PN
commands from the command line interface on the serial port.
Session Timeout and Priority
The XL-GPS’s system firmware has session timers that will terminate an inactive command
line session on the network port after 15 minutes. The XL-GPS does not terminate inactive
command line sessions on the serial port.
The user can open a network port session and a serial ports session concurrently, provided
the other session is inactive (i.e., not actively performing a function such as See "F8 –
Continuous Time Once-per-Second" on page 60).The XL-GPS does not allow two or more
concurrent network port sessions.
A network port session can be used while a serial port session is open. However, if the serial
port session receives user input at this point, it takes control away from the network port and
does not yield control to the network port again. The network port will show a prompt, but will
not accept additional commands after the serial port has taken control back. At this point,
closing the network port connection and opening a new one will also fail; a network port
connection cannot be re-established until the serial port has been closed. The following
transcripts show the results of a ‘contest’ between a serial and a network port session:
