       srec_ascii_hex - Ascii‐Hex file format


       This  format  is  also  known as the AsciiSpaceHex or AsciiHexSpace
       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[rq] to be loaded at address 0x1000.
              ^B $A1000,
              48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 0A ^C
