Tip (unix Utility)
tip is a Unix utility for establishing a terminal connection to a remote system via a modem. It is commonly associated with BSD Unix, as well as other UNIX operating systems such as Sun's Solaris. It was originally included with 4.2BSD. The name may refer to ARPANET's Terminal Interface Processor (TIP), a variant of the IMP, used to connect serial terminals directly with ARPANET. tip is referred to in the Solaris documentation as the preferred terminal emulator to connect to a Sun workstation's serial port for maintenance purposes, for example, to configure the OpenPROM firmware. Basics tip is one of the commands referenced in the expect reference book by Don Libes. The tip command line options are as follows: tip v speed-entry( , , ) Use ~. to exit. Use ~# to break (Stop-A on a Sun keyboard). Use ~? to list all commands. Examples This Expect script is a simple example that establishes a terminal session: spawn tip modem expect "connected" send "ATD$argc\r" set timeou ...

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Expect
Expect is an extension to the Tcl scripting language written by Don Libes. The program automates interactions with programs that expose a text terminal interface. Expect, originally written in 1990 for the Unix platform, has since become available for Microsoft Windows and other systems. Basics Expect is used to automate control of interactive applications such as Telnet, FTP, passwd, fsck, rlogin, tip, SSH, and others. Expect uses pseudo terminals (Unix) or emulates a console (Windows), starts the target program, and then communicates with it, just as a human would, via the terminal or console interface. Tk, another Tcl extension, can be used to provide a GUI. Usage Expect serves as a "glue" to link existing utilities together. The general idea is to figure out how to make Expect use the system's existing tools rather than figure out how to solve a problem inside of Expect. A key usage of Expect involves commercial software products. Many of these products provide so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cu (Unix Utility)
cu ("call Unix") is a Unix utility for establishing a connection between two computer systems via a serial port to another computer system. When cu was originally created, connections to remote systems were most often done by phone, and cu was used in conjunction with UUCP utilities to transfer data via a modem. Now that intersystem communications are much more easily and reliably handled via Internet connections, its more typical use is to establish a terminal connection to another system via a modem or direct cabling. It was originally released as part of the 4.2BSD Unix operating system in 1983. In the same year, it was one of several UNIX tools available for Charles River Data Systems' UNOS operating system under Bell Laboratories license. In the following years it was included in many Unix and Unix-like operating systems, including Solaris and Linux Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating syst ...

Script (Unix)
The script command is a Unix utility that records a terminal session. It dates back to the 1979 3.0 Berkeley Software Distribution (BSD). Usage A script session is captured in file name by default; to specify a different filename follow the command with a space and the filename as such: . The recorded format of consists of plain-text timing information (for the whole session) and verbatim command output, including whatever ANSI escape code the program has printed for formatting. It uses a pseudoterminal for this purpose, so programs act exactly as if they were on a terminal. The util-linux command offers a replay function to its script, which supports using an extra timing file for character-level information. Some online services, such as the now-defunct shelr.tv, can also show the format as a low-bandwidth alternative to video screencasts. Problems with script command One of the problems with the script command is that it only allows logging of a child process; and oft ...

Minicom
Minicom is a text-based modem control and terminal emulator program for Unix-like operating systems including Cygwin, originally written by Miquel van Smoorenburg, and modeled somewhat after the popular MS-DOS program Telix but is open source. Minicom includes a dialing directory, ANSI and VT100 emulation, an (external) scripting language, and other features. Minicom is a menu-driven communications program. It also has an auto ZMODEM download. It now comes packaged in most major Linux distribution repositories such as Debian, Ubuntu and Arch Linux. A common use for Minicom is when setting up a remote serial console, perhaps as a last resort to access a computer if the LAN is down. This can be done using nothing more than a 386 laptop with a Minicom floppy distribution such as Pitux or Serial Terminal Linux. For this purpose, though, one may use Kermit on DOS, such as FreeDOS, does not need Linux so can use a 286 or possibly an 8086 or 8088. Minicom is useful to creat ...

OpenPROM
Open Firmware is a standard defining the interfaces of a computer firmware system, formerly endorsed by the Institute of Electrical and Electronics Engineers (IEEE). It originated at Sun Microsystems where it was known as OpenBoot, and has been used by multiple vendors including Sun, Apple, IBM and ARM. Open Firmware allows a system to load platform-independent drivers directly from a PCI device, improving compatibility. Open Firmware may be accessed through its command line interface, which uses the Forth programming language. History Open Firmware was described by IEEE standard as ''IEEE 1275-1994''. This standard was not reaffirmed by the Open Firmware Working Group (OFWG) since 1998, and was therefore officially withdrawn by IEEE in May 2005. Features Open Firmware defines a standard way to describe the hardware configuration of a system, called the ''device tree''. This helps the operating system to better understand the configuration of the host computer, relyi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Terminal Emulator
A terminal emulator, or terminal application, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term ''terminal'' covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window. A terminal window allows the user access to a text terminal and all its applications such as command-line interfaces (CLI) and text user interface (TUI) applications. These may be running either on the same machine or on a different one via telnet, ssh, dial-up, or over a direct serial connection. On Unix-like operating systems, it is common to have one or more terminal windows connected to the local machine. Terminals usually support a set of escape sequences for controlling color, cursor position, etc. Examples include the family of terminal control sequence standards that includes ECMA-48, ANSI X3.64, ...

Sun Workstation
The SUN workstation was a modular computer system designed at Stanford University in the early 1980s. It became the seed technology for many commercial products, including the original workstations from Sun Microsystems. History In 1979 Xerox donated some Alto computers, developed at their Palo Alto Research Center, to Stanford's Computer Science Department, as well as other universities that were developing the early Internet. The Altos were connected using Ethernet to form several local area networks. The SUN's design was inspired by that of the Alto, but used lower-cost modular components. (Many words are spelled phonetically) The project name was derived from the initials of the campus' Stanford University Network. CSL Technical Report 229 (First author name is misspelled on cover) Professor Forest Baskett suggested the best-known configuration: a relatively low-cost personal workstation for computer-aided logic design work. The design created a 3M computer: a 1 million ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interface Message Processor
The Interface Message Processor (IMP) was the packet switching node used to interconnect participant networks to the ARPANET from the late 1960s to 1989. It was the first generation of gateways, which are known today as routers. An IMP was a ruggedized Honeywell DDP-516 minicomputer with special-purpose interfaces and software. In later years the IMPs were made from the non-ruggedized Honeywell 316 which could handle two-thirds of the communication traffic at approximately one-half the cost. An IMP requires the connection to a host computer via a special bit- serial interface, defined in '' BBN Report 1822''. The IMP software and the ARPA network communications protocol running on the IMPs was discussed in , the first of a series of standardization documents published by what later became the Internet Engineering Task Force (IETF). History The concept of an interface computer for computer networking was first proposed in 1966 by Donald Davies for the NPL network in England ...
