NOTES:

The command packet must always be exactly forty-eight bytes long.

All unused characters should be set to NULL (0x00).

All characters must be upper case and exactly as shown, including spaces.

Numbers, if required, must follow the COMMAND STRING without any
spacing in ASCII format.

Checksum must be computed as follows (must have the CRC Table
available from Scientific Test Inc.):
void init_crc32( unsigned long *crc )
{
*crc = 0xffffffff;
}
void update_crc32( unsigned long *crc, unsigned char ch )
{
int k;
k = ( *crc ^ ch ) & 0x000000ffL;
*crc = (( *crc >> 8 ) & 0x00ffffffL ) ^ crc32_table[k];
}

