Record Type specifies the command type. This field is used to interpret the
remaining information within the frame. The encoding for all the current
record types are described in Table 51.
Data/Info is a 64 bytes length field. It consists of 64 bytes encoded as pairs
of hexadecimal digits. The meaning of data depends on the Record Type.
The two’s complement of the 8-bit bytes that result from converting each pair
of ASCII hexadecimal digits to one byte of binary, and including the Reclen
field to and including the last byte of the Data/Info field. Therefore, the sum
of all the ASCII pairs in a record after converting to binary, from the Reclen
field to and including the Checksum field, is zero.
1. A data byte is represented by two ASCII characters.
2. When the field Load Offset is not used, it should be coded as 2 bytes (00h 00h).
