18 Depending on in_voltageY_sensing_mode the low voltage threshold
19 is separately set for "GND-Open" and "Supply-Open" modes.
20 Channels 0..31 have common low threshold values, but could have different
23 The low voltage threshold range is between 2..21V.

33 As far as known the uGuru is always placed at and using the (ISA) I/O-ports
34 0xE0 and 0xE4, so we don't have to scan any port-range, just check what the two
35 ports are holding for detection. We will refer to 0xE0 as CMD (command-port)
39 present. We have to check for two different values at data-port, because
41 later on attached again data-port will hold 0x08, more about this later.
