srec_tektronix(5)	      File Formats Manual	     srec_tektronix(5)

NAME
       srec_tektronix -	Tektronix hexadecimal file format

DESCRIPTION
       The  Tektronix  hexadecimal  file  format is no longer very common.  It
       serves a	similar	purpose	to the Motorola	 and  Intel  formats,  usually
       used to transfer	data into EPROM	programmers.

   The Lines
       Most Tektronix hex files	contain	only Tektronix hex lines (see the next
       section), which always start with a slash  ("/[rq])  character.	 There
       are only	two types of lines - data lines	and a termination line.

   Data	Lines
       Data  lines  have  five	fields:	 address, length, checksum 1, data and
       checksum	2.  The	lines always start with	a slash	("/[rq]) character.

		+--+---------+--------+-----------+------+-----------+
		|/ | Address | Length |	Checksum1 | Data | Checksum2 |
		+--+---------+--------+-----------+------+-----------+
       Address This is a 4 character (2	byte) address that specifies where the
	       data in the record is to	be loaded into memory.

       Data Length
	       The  data  length  field	 is  a 2 character (1 byte) field that
	       specifies the number of character pairs	(bytes)	 in  the  data
	       field.  This field never	has a value of zero.

       Checksum	1
	       The  checksum  1	 field	is  a 2	character (1 byte) field.  Its
	       value is	the 8-bit sum of the six 4-bit values  which  make  up
	       the address and length fields.

       Data    The  data field contains	character pairs	(bytes); the number of
	       character pairs (bytes) is indicated by the length field.

       Checksum	2
	       The checksum 2 field is a 2  character  (1  byte)  field.   Its
	       value  is  the least significant	byte of	the sum	of the all the
	       4-bit values of the data	field.

   Termination Line
       Termination lines have three fields: address, zero and  checksum.   The
       lines always start with a slash ("/[rq])	character.

			   +--+---------+------+----------+
			   |/ |	Address	| Zero | Checksum |
			   +--+---------+------+----------+
       Address This  is	a 4 character (2 byte) address that specifies where to
	       begin execution.

       Zero    The data	length field is	a 2 character (1 byte) field of	 value
	       zero.

       Checksum
	       The  checksum  1	 field	is  a 2	character (1 byte) field.  Its
	       value is	the 8-bit sum of the six 4-bit values  which  make  up
	       the address and zero fields.

   Size	Multiplier
       In general, binary data will expand in sized by approximately 2.4 times
       when represented	with this format.

EXAMPLE
       Here is an example Tektronix hex	file.  It contains  the	 data  "Hello,
       World[rq] to be loaded at address 0.
	      /00000D0D48656C6C6F2C20576F726C640A52
	      /00000000
