NAME

       srec_ascii_hex - Ascii-Hex file format

DESCRIPTION

       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, too.

       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, 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.

EXAMPLE

       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
