This field specifies the number of bytes of the parameter value.
The content of the parameter value is an ASCII string which describes the error
event. The text of the parameter includes a "Packet #," which is a value from 0 to
255. This internal number is assigned when the packet is written into EEPROM.
Zero is normally the oldest packet, but packet numbers can wrap around from 255
to 0.
