modem:
Sample:
When the tracking unit is in normal operating mode the tracking unit requires the four-digit
password code (can be configured in the GPS Tracking configuration menu. Default is
‘1234') to return to Diagnostic mode after it receives the
'X' or 'x' command from
the serial port.
The password must be entered after the tracking unit sends the
'OK0' or 'OK1' command.
The correct password must be followed by <CR> (ENTER) to confirm password entered.
You must enter the correct password within 8 seconds or the tracking unit will return to
normal operating mode.
When in ‘Normal’ running mode the serial data communication between the GSM modem
and the CPU is directly send to the serial port. This allows the user to monitor or capture
the data.
Problems related to communication errors can also be easy detected.
