   Man page i2cdetect.8: Scanning range can be restricted
+  Programs i2cdetect, i2cdump, isadump: Flush output in real time
   Program sensors-detect: Only probe relevant I2C addresses
                           Drop ARP-capable device detection
                           Add Maxim MAX6655/MAX6656 detection
