The character Xoff (hex 13) on the serial line stops the data unloading in progress.
The character Xon (hex 11) reactivates the suspended data unloading in progress.
Dumping data from the memory
Press the PROG key twice until P1 appears on the display.
Press the ENTER key.
The instrument continues to show P1 on the display and dumps the data from the instrument’s
internal memory through the serial line.
