Document Structure  

• ACP-QIO Interface describes the Queue I/O (QIO) interface to file system ancillary control processes (ACPs).



• Chapters 2 through 9 describe the use of file-structured and real-time I/O device drivers, the drivers for storage devices such as disks and magnetic tapes, and supported terminal devices:

  Disk Drivers discusses the disk drivers.

  Magnetic Tape Drivers discusses the magnetic tape drivers.

  Mailbox Driver discusses the mailbox driver.

  Terminal Driver discusses the terminal driver.

  Pseudoterminal Driver discusses the pseudoterminal driver.

  Shadow-Set Virtual Unit Driver discusses the shadow-set virtual unit driver.

  Using the OpenVMS Generic SCSI Class Driver discusses the Generic Small Computer System Interface (SCSI) class driver.

  Local Area Network (LAN) Device Drivers discusses the local area network (LAN) device drivers.




• Optional Features for Improving I/O Performance describes optional features to improve OpenVMS Alpha I/O performance.



• I/O Function Codes summarizes the QIO function codes, arguments, and function modifiers used by the drivers listed previously.



• IO$_DIAGNOSE Function for SCSI Class Drivers describes the enhanced IO$_DIAGNOSE function for SCSI class drivers.



• lists the DEC Multinational character set and the ANSI and DIGITAL private escape sequences for terminals.



• Control Connection Routines describes the calling conventions for the pseudoterminal driver's control connection routines.
