       srec_ascii_hex -	Ascii-Hex file format

       This  format  is	 also  known as	the Ascii-Space-Hex or Ascii-Hex-Space
       format.	If you know who	invented this format, please let me know.   If
       you  have a better or more complete description,	I'd like to know that,

       The file	starts with  a	start-of-text  (STX  or	 Control-B)  character
       (0x02).	Everything before the STX is ignored.

       Each  data byte is represented as 2 hexadecimal characters, followed by
       an "execution character".  The default execution	character is a	space,
       although	many programs which write this format omit the space character
       immediately preceding end-of-line.

       The address for data bytes is set by using a sequence of	$Annnn,	 char-
       acters,	where  nnnn is the 4-character ascii representation of the ad-
       dress.  The comma is required.  There is	no need	for an address	record
       unless  there  are gaps.	 Implicitly, the file starts a address 0 if no
       address is set before the first data byte.

       The file	ends with an end-of-text (ETX or Control-C) character  (0x03).
       Everything following the	ETX is ignored.

       It  is  also  possible to specify a running 16-bit checksum using a se-
       quence of $Snnnn, characters, although this usually appears  after  the
       ETX character and is thus often ignored.

   Variant Forms
       In  addition  to	a space	character, the execution character can also be
       percent (%) called "ascii-hex-percent" format, apostrophe (') or	 comma
       (,) called "ascii-hex-comma" format.  The file must use the same	execu-
       tion character throughout.

       If the execution	character is a comma, the address  and	checksum  com-
       mands are terminated by a dot (.) rather	than a comma (,).

   Size	Multiplier
       In general, binary data will expand in sized by approximately 3.0 times
       when represented	with this format.

       Here is an example  ascii-hex  file.   It  contains  the	 data  "Hello,
       World[rq] to be loaded at address 0x1000.
	      ^B $A1000,
	      48 65 6C 6C 6F 2C	20 57 6F 72 6C 64 0A ^C
