NAME
       srec_emon52 - Elektor Monitor (EMON52) file format

DESCRIPTION
       This  format  is	 used by the monitor EMON52, developed by the European
       electronics magazine Elektor (Elektuur in Holland).   Elektor  wouldn't
       be  Elektor  if	they didn't try	to reinvent the	wheel.	It's a mystery
       why they	didn't use an existing format for the project.	Only the Elek-
       tor Assembler will produce this file format, reducing the choice	of de-
       velopment tools dramatically.

   Records
       All data	lines are called records, and each record contains the follow-
       ing four	fields:

			 +---+------+---+-----------+------+
			 |cc | aaaa | :	| dd ... dd | ssss |
       The field are defined-as-follows:+-----------+------+

       cc      The  byte  count.  A two	digit hex value	(1 byte), counting the
	       actual data bytes in the	record.	 The byte count	 is  separated
	       from the	next field by a	space.

       aaaa    The address field.  A four hex digit (2 byte) number represent-
	       ing the first address to	be used	by this	record.

       :       The address field and the data field are	separated by a colon.

       dd      The actual data of this record.	There can be  1	 to  255  data
	       bytes per record	(see cc) All bytes in the record are separated
	       from each other (and the	checksum) by a space.

       ssss    Data Checksum, adding all bytes	of  the	 data  line  together,
	       forming	a  16 bit checksum.  Covers only all the data bytes of
	       this record.

       Please note that	there is no End	Of File	record defined.

   Byte	Count
       The byte	count cc counts	the actual data	bytes in the  current  record.
       Usually records have 16 data bytes.  I don't know what the maximum num-
       ber of data bytes is.  It depends on the	size of	the data buffer	in the
       EMON52.

   Address Field
       This  is	 the address where the first data byte of the record should be
       stored.	After storing that data	byte, the address is incremented by  1
       to  point  to the address for the next data byte	of the record.	And so
       on, until all data bytes	are stored.

       The address is represented by a 4 digit hex number (2 bytes), with  the
       MSD first.

   Data	Field
       The  payload  of	the record is formed by	the Data field.	 The number of
       data bytes expected is given by the Byte	Count field.

   Checksum
       The checksum is a 16 bit	result from  adding  all  data	bytes  of  the
       record together.

   Size	Multiplier
       In general, binary data will expand in sized by approximately 3.8 times
       when represented	with this format.

EXAMPLE
       Here is an example of an	EMON52 file:
	      10 0000:57 6F 77 21 20 44	69 64 20 79 6F 75 20 72	65 61 0564
	      10 0010:6C 6C 79 20 67 6F	20 74 68 72 6F 75 67 68	20 61 05E9
	      10 0020:6C 6C 20 74 68 69	73 20 74 72 6F 75 62 6C	65 20 05ED
	      10 0030:74 6F 20 72 65 61	64 20 74 68 69 73 20 73	74 72 05F0
	      04 0040:69 6E 67 21 015F
