SA - Serial Analyzer, Continued

Buffered Data The serial analyzer does not display data immediately. It buffers the data so that the serial analyzer remains non-intrusive. The buffer is large enough (1000 bytes) that overflow is unlikely. If the buffer does overflow, however, the indication provided is:

buffer overflow

The monitor discards incoming data as long as the buffer is in the overflow state. It does not destroy the current buffer contents.
