       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, followd by
       an "execution character".  The default execution character is a  space,
       although many programs which write this format omit the space character
       immediately preceeding end-of-line.

       The address for data bytes is  set  by  using  a  sequence  of  $Annnn,
       characters,  where  nnnn is the 4-character ascii representation of the
       address.  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
       sequence 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
       execution character throughout.

       If the execution  character  is  a  comma,  the  address  and  checksum
       commands 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’’ to be loaded at address 0x1000.
              ^B $A1000,
              48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 0A ^C
