+ * Motorola S-Record Format:
+ *
+ * Motorola S-Records are an industry-standard format for
+ * transmitting binary files to target systems and PROM
+ * programmers. LSI Logic have extended this standard to include
+ * an S4-record containing an address and a symbol.
+ *
+ * The extended S-record standard is as follows:
+ *
+ * S<type><length><address><data....><checksum>
+ * S4<length><address><name>,<checksum>
+ *
+ * Where:
+ *
+ * type
+ *     is the record type. Where:
+ *
+ *     0  starting record (optional)
+ *     1  data record with 16-bit address
+ *     2  data record with 24-bit address
+ *     3  data record with 32-bit address
+ *     4  symbol record (LSI extension)
+ *     5  number of data records in preceeding block
+ *     6  unused
+ *     7  ending record for S3 records
+ *     8  ending record for S2 records
+ *     9  ending record for S1 records
+ *
+ * length
+ *     is two hex characters. This defines the length of the
+ *     record in bytes (not characters). It includes the address
+ *     field, the data field, and the checksum field.
+ *
+ * address
+ *     is 4, 6, or 8 characters. Corresponding to a 16-, 24-, or
+ *     32-bit address. The address field for S4 records is
+ *     always 32 bits.
+ *
+ * data
+ *
+ *     Are the data bytes. Each pair of hex characters represent
+ *     one byte in memory.
+ *
+ * name
+ *     Is the symbol name. The symbol is terminated by a ','.
+ *
+ * checksum
+ *     Is the one's complement of the 8-bit checksum.
+ *
+ * Example
+ *
+ * S0030000FC
+ * .
+ * .
+ * S325000004403C0880018D08DD900000000011000026000000003C0880012508DC50C50000B401
+ * S32500000460C50100B8C50200BCC50300C0C50400C4C50500C8C50600CCC50700D0C50800D4FA
+ * S32500000480C50900D8C50A00DCC50B00E0C50C00E4C50D00E8C50E00ECC50F00F0C51000F49A
+ * S325000004A0C51100F8C51200FCC5130100C5140104C5150108C516010CC5170110C518011434
+ * .
+ * .
+ * S70500000000FA
+ *
+ * The S0 record starts the file. The S3 records contain the
+ * data. The S7 record contains the entry address and terminates
+ * the download.
