The General Purpose I/O package (GPIO) contains all the system
calls for controlling the I/O bus for multibus, VME bus, AT bus
and SCSI periperals. There are a series of calls contained in
the library that a specifically for SCSI devices:

procedure scsi_$abort_operation(               { abort operation }

procedure scsi_$acquire(                       { acquire device }

procedure scsi_$acquire_stream(                { acquire device }

procedure scsi_$do_command(                    { do scsi command }

procedure scsi_$get_ec(                        { get device eventcount }

procedure scsi_$get_info(                      { get implementation information }

procedure scsi_$release(                       { release device }

procedure scsi_$reset_device(                  { reset scsi device }

procedure scsi_$unwire(                        { unwire buffer }

function scsi_$wait(                           { wait for operation to complete }

procedure scsi_$wire(                          { wire buffer }


The complete call definitions can be found in /sys/ins/scsi.ins.pas
if you have GPIO installed (it is an optional product).
