drain(7) -- capture unimplemented link-layer protocols
|
|
The Drain protocol provides non-promiscuous capture of packets having unimplemented link-layer protocol types, i.e., packets that the operating system normally receives and drops ``down the drain''. It treats packets as datagrams containing a link-layer header followed by data. Drain uses the Raw address format, interpreting ports as link-layer type codes (in host byte order) to match against unimplemented types in received packets. Multiple sockets may bind to the same port on a network inter... |

ds(7) -- generic (user mode) SCSI driver
|
|
The ds interface provides user-mode access to the SCSI bus. It supports the programming interfaces described in dslib(3) and below. All of the ds devices support the same general interface. The program calls open, gaining exclusive use of a specified SCSI device (that is, two processes may not both have the same device open at the same time via this driver). Additionally, when the O_EXCL open flag set, exclusive use of the target will be acquired. No other SCSI driver will be able to use the tar... |

duart(7) -- on-board serial ports
|
|
Each IRIS-4D system uses a DUART to connect the mouse and the keyboard. Most models are also equipped with some number of additional `on-board' serial ports. The Indigo, Indy, Indigo2, O2 and OCTANE have two ports; and the Onyx and the Challenge can be configured with as few as four serial ports and as many as 16. The first of these ports, /dev/ttyd1, is often used for the `serial' or `debugging' console. Other ports are commonly used for serial terminal connections, modems, a dial-and-button... |

/hw/net/egN special file |
|
ei(7) -- external interrupts interface
|
|
The special files in /dev/external_int provide access to the external interrupt interface on those machines which have such an interface. This interface allows separate machines to send and receive interrupts over a dedicated wire for purposes of inter-machine synchronization. Using this device, a user process may generate outgoing interrupts to other machines, or receive interrupts from other machines in a variety of ways: the user process may request to block in an ioctl() until an interrupt i... |

ethernet(7) -- Ethernet controllers
|
|
Various error messages are printed by the kernel when a problem is encountered. The message is preceded by the controller name, for example, et0. Serious errors are flagged with a dagger (-). If they occur repeatedly, contact your product support service for assistance. By default, many non-serious errors will not cause a diagnostic message to be displayed on the console. To enable all driver diag messages, use the command ifconfig xxx debug where xxx is the ethernet network interface name. The ... |

failover(7) -- disk device alternate path support
|
|
Failover creates an infrastructure for the definition and management of multiple paths to a single disk device or lun. This failover infrastructure is used by an SGI logical volume manager (XLV, XVM) to select the path used for access to the logical volume(s) created on the storage device(s). In the presense of i/o errors, the SGI logical volume manager will request from the failover infrastructure a new path to be used for access to the erring logical volumes. This path failover requires the lo... |

files(7) -- local files name service parser library
|
|
The files client library parses traditional local name service configuration files such as /etc/passwd and makes the data available through the nsd(1M) filesystem. This library is meant to be used only by the nsd(1M) daemon to efficiently access local name service data. The library /var/ns/lib/libns_files.so is opened by the nsd(1M) daemon when files is listed as the protocol for some map in a nsswitch.conf file. Extended attributes in the nsswitch.conf file can be used to control the behavior o... |

fsctl(7) -- operations on a mounted file system
|
|
fsctl presents a device interface for performing low-level operations on a mounted file system. This driver is used by the file system reorganizer, fsr. WARNING: this driver does NOT copy or otherwise operate on data within file system blocks. This can be done through the raw device interface to the file system. Only the superuser can open /dev/fsctl. Only one process at a time can open this device. The following operations are available as ioctl(2) calls on a file descriptor opened on this devi... |

genlock(7) -- genlock capability on IRIS-4D Series machines
|
|
In some multi-screen stereo applications it is desirable to genlock stereo screens together. Care must be taken to ensure that right-eye views are locked together. For some older stereo formats, this may require several attemps; the system may lock the left eye of one screen to the right eye of the other. If this occurs, turn genlock off and try the genlock again. Removing and reconnecting the sync signal from the sync input is not suggested, as this may cause problems with the hardware. Genlock... |

gvo(7) -- Serial digital video option for Onyx InfiniteReality graphics
|
|
In low-latency mode, a suitable genlock signal must be supplied, or the GVO will not function correctly. in low-bandwidth mode, the source channel must have a frame rate that is faster than the GVO field rate (59.94 frames/sec NTSC, 50.00 frames/sec PAL) Page 1 GVO(7) GVO(7) |

hitachi(7) -- driver for Hitachi HDG-J series tablets
|
|
This driver is for the Hitachi HDG-J series of tablets. It will probably also work on other hitachi tablets capable of running in Hitachi III mode. It operates the tablets in high-resolution mode to provide for smooth drawing. These tablets provide x, y, height, pressure and tilt information. The driver uses hitachi as the X name of the device. (See input(7).) The difference between this drive and the driver called tablet, which is also for Hitachi tablets, is the use of high-resolution operatio... |

icmp(7) -- Internet Control Message Protocol
|
|
ICMP is the error and control message protocol used by IP and the Internet protocol family. It may be accessed through a "raw socket" for network monitoring and diagnostic functions. The proto parameter to the socket call to create an ICMP socket is obtained from getprotobyname(3N). ICMP sockets are connectionless, and are normally used with the sendto and recvfrom calls, though the connect(2) call may also be used to fix the destination for future packets (in which case the read(2) or recv(2)... |

ik(7) -- Ikon 10088 (ikc) parallel interface controller
|
|
This is the driver for the Ikon 10088 (and 10088A) parallel interface controller. The controller can support any one of three possible interfaces: Versatec TTL, Versatec differential, or (Tektronixcompatible) Centronics. The Ikon controller board must be jumpered, switched, connected, and terminated differently depending on which interface is being used. If the board is configured for the Centronics interface, bytes written to /dev/cent are output to the parallel port. A printer reset (input pri... |
