UART/RS232 Totalizer

306
The UART/RS232 totalizer consists of counters that provide a
direct measure of bus quality and efficiency. The totalizer
appears on screen whenever UART/RS232 Decode is ON in the
Serial Decode Menu.
The totalizer is running, counting frames and calculating the
percentage of error frames, even when the oscilloscope is
stopped (not acquiring data).
The ERR (error) counter is a count of Rx and Tx frames with
parity errors. The TX FRAMES and RX FRAMES counts include
both normal frames and frames with parity errors. When an
overflow condition occurs, the counter displays OVERFLOW.
The counters can be reset to zero by pressing the Reset UART
Counters softkey.
