+ *
+ * memPIO is a USB-interface with 3 8bit ports
+ * each port can be either input or output
+ * (honestly: port3 is divided into 2 subports of 4bits with independent directions,
+ * however, this is not yet implemented)
+ *
+ *
+ * "mode <port0> <port1> <port2> <port3>" : mode can be either 0 (input) or 1 (output)
+ * "mode <allports>": like above, but set all ports at once to the same value
+ * "bang": manual polling
+ * "set <val0> <val1> <val2> <val3>": write values to ports in output-mode
+ * "set <val>" write the same value to all ports
+ *
+ * TODO: currently two [memPIO]s interfere
+ *
