+ * Parse one out of four values of a four-display Metex14 variant.
+ *
+ * The caller's 'info' parameter can be used to track the channel index,
+ * as long as the information is kept across calls to the 14-byte packet
+ * parse routine (which clears the 'info' container).
+ *
+ * Since analog values have further details in the 'analog' parameter,
+ * passing multiple values per parse routine call is problematic. So we
+ * prefer the approach of passing one value per call, which is most
+ * reliable and shall fit every similar device with multiple displays.
+ *
+ * The meters which use this parse routine send one 14-byte packet per
+ * display. Each packet has the regular Metex14 layout.
