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 val-
	       ues 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

NAME

       srec_wilson - wilson file format

DESCRIPTION

       This is a mystery format, added to support a mysery EPROM loader used by Alan Wilson <dvdsales@dvdlibrary.co.uk>

       If  you know the true name of this format, please let me know!  It bears a remarkable similarity to the Motorola S-Record format, however I
       can find no reference to a "compressed" Motorola format.

   The Lines
       Each line contains normal ASCII characters, and "high bit on[rq] characters, but the ASCII control characters are avoided (the  high-bit-on
       con characters are not avoided).  Normal line termination characters (CRLF or LF, depending on your system) are used.

       The  presence  of  high-bit-on  characters  makes this format unattractive to send via email, as it must be wrapped as a binary attachment,
       increasing its size.

       In general, a single byte per byte is used to encode values, however some values use two bytes, according to the following table:

							  Byte Value	Encoding (1 or 2 chars)
							 0x00 .. 0x9F	     0x40 .. 0xDF
							 0xA0 .. 0xAF	0x3A 0x30 .. 0x3A 0x3F
							 0xB0 .. 0xBF	0x3B 0x30 .. 0x3B 0x3F
							 0xC0 .. 0xCF	0x3C 0x30 .. 0x3C 0x3F
							 0xD0 .. 0xDF	0x3D 0x30 .. 0x3D 0x3F
							 oxE0 .. 0xFF	     0xE0 .. 0xFF
       The rest of this description, when refering to "bytes[rq] means byte values encoded using the above table.

   The Fields
       Each line consists of 5 fields. These are the type field, length field, address field, data field, and the checksum.

						   +-----+---------------+---------+------+----------+
						   |Type | Record Length | Address | Data | Checksum |
						   +-----+---------------+---------+------+----------+
       Type    The type field is a 1 character field that specifies whether the record is data (0x43), or termination (0x47).

       Record Length
	       The record length field is a 1 byte field that specifies the number of bytes in the record, excluding the type  and  record  length
	       fields.

       Address This is a 4-byte address that specifies where the data is to be loaded into memory.

       Data    The data field contains the executable code, memory-loadable data or descriptive information to be transferred.

       Checksum
	       The  checksum is an 1-byte field that represents the least significant byte of the one's complement of the sum of the values repre-
	       sented by the bytes making up the length, address, and data fields.

   Record Types
       0x43 (#)
	       A record containing data and the 4-byte address at which the data is to reside.

       0x47 (')
	       A termination record.  The address field may contain the 4-byte address of the instruction to which control is passed.  There is no
	       data field.

   Size Multiplier
       In general, binary data will expand in sized by approximately 1.5 times when represented with this format.
