pfto(7) -- Powerfail Timeout
|
|
HP-UX SCSI disk device drivers have a timeout facility that detects non-responding disks. VxVM uses this mechanism in its Powerfail Timeout (pfto) feature. You can specify a timeout value for individual VxVM disks using the vxdisk command (see the EXAMPLES section below). If a disk fails to respond in the specified timeout period, the driver receives a timer interrupt. pfto values are persistent a... |

poll(7) -- monitor I/O conditions on multiple file descriptors
|
|
/dev/poll provides an interface to the event port driver allowing a user to synchronously monitor a specific set of conditions associated with a registered set of file descriptors. Poll conditions include the ability to read or write data without blocking and certain exceptional conditions. Access to /dev/poll is provided through the open(), write(), and ioctl() system calls. The /dev/poll event p... |

ps2(7) -- PS/2 keyboard/mouse device driver and files
|
|
The ps2 driver allows the use of IBM Personal System/2 (PS/2) compatible keyboards and mouse devices on Hewlett-Packard workstations equipped with PS/2 interface hardware. On systems with a single interface, PS/2 device file names use the following format: /dev/ps2_n where n where n represents the interface port number, ranging from 0 to 15. For example, the device file /dev/ps2_1 is used to acces... |

ptem(7) -- STREAMS pty (pesudo-terminal) Emulation module
|
|
ptem is a STREAMS module that emulates a terminal when used in conjunction with ldterm (STREAMS line discipline) and pts (STREAMS slave pty driver). The ptem module normally sits above pts and below ldterm. The user process must push the ptem module onto the slave side of the pty with a call to the STREAMS I_PUSH ioctl(2) system call before ldterm is pushed. ptem is responsible for processing all ... |

ptm(7) -- STREAMS master pty (pseudo-terminal) driver
|
|
A pseudo-terminal (pty) consists of a tightly-coupled pair of character devices, called the master device and slave device. The pty master and slave device drivers work together to simulate a terminal connection where the master provides a connection to the pseudo terminal server process and the slave provides a terminal device special file access for the terminal application processes, as depicte... |

|
pty(7) -- pseudo terminal driver
|
|
The pty driver provides support for a device-pair termed a pseudo terminal. A pseudo terminal is a pair of character devices, a master device and a slave device. The slave device provides to application processes an interface identical to that described in termio(7). Unlike all other devices that provide the interface described in termio(7), the slave device does not have a hardware device behind ... |
|
random(7) -- strong random number generator
|
|
The character special files /dev/random and /dev/urandom provide an interface to the kernel-resident random number generator, rng. A read() from /dev/random is potentially blocking, as compared to a read from /dev/urandom which is always nonblocking. Data from /dev/urandom can potentially have lower entropy than data from /dev/random. The rng module is a dynamically loadable kernel module (DLKM). ... |

routing(7) -- system support for local network packet routing
|
|
The network facilities for HP-UX provide general packet routing support. Routing table maintenance is handled by application processes. A routing table consists of a set of data structures used by the network facilities to select the appropriate remote host or gateway when transmitting packets. The table contains a single entry for each route to a specific network or host, as displayed by the nets... |
|
sad(7) -- STREAMS Administrative Driver
|
|
The sad driver provides an interface to the autopush facility using the ioctl() function. As an interface, the sad driver enables administrative tasks to be performed on STREAMS modules and drivers. By specifying the command parameter to the ioctl() function, an administrator can configure autopush information for a device, get information on a device, or check a list of modules. fildes is a file ... |

scsi(7) -- Small Computer System Interface device drivers
|
|
The Small Computer System Interface (SCSI) is an American National Standard for interconnecting computers and peripheral devices. HP-UX supports the SCSI device protocol on parallel SCSI interfaces (see ANSI Std X3.131-199X, ``SCSI-3'') and Fibre Channel interfaces (see ANSI Std X3.269-199X, "Fibre Channel Protocol for SCSI"). The SCSI standard includes specifications for a variety of device t... |

scsi_ctl(7) -- SCSI pass-through driver
|
|
SCSI devices are controlled by a device-specific driver, when one exists. Device-specific drivers, such as those for SCSI direct access (disk) and sequential access (tape) devices, coordinate device and driver states to accomplish correct logical device behavior. The scsi_ctl pass-through driver enables use of SCSI devices and commands not normally supported by these device-specific drivers. Depen... |
