This driver concept is intended to enable calling of memory-resident 
device drivers of various types from any desired programs. The 
communication between the programs and the drivers takes place via a 
data structure made available by the driver. A fixed kernel for the 
data structure is prescribed for this, which must be adhered to by all 
drivers that comply with this standard. In addition, some extensions 
are possible. From the version numbers the calling program then can 
establish if and which extensions of the data structure are present. 
All data structures are upwardly compatible.

  1. Preliminary remarks

     All values that require more than 1 byte are defined always in 
     the order MSB...LSB. The sample codes are formulated in 68000 
     Assembler. The description for ATARI ST follows.
