Popcom Ports
Popcom (an abbreviation of Popular Communications) was a line of modems marketed by the Prentice Corporation of Sunnyvale, California, introduced in 1984. The line comprised six models—X100, X150, C100, C150, C200, C250—the ''C'' models being internal modems meant to plug into a free ISA expansion slot of a PC compatible, while the ''X'' models were compact external units intended to be plugged into a wall indefinitely and connected to the computer via a serial cable. The X100 and X150 were noted by the press for their very small physical footprint among its contemporaries in the market. The whole line-up of modems were largely compatible with the Hayes command set for modem–computer communication, although Prentice programmed an extended feature set onto their ROMs, which allowed the modems to recover from temporary hiccups in transmissions and switch between voice communication and data transmission nearly on-the-fly. Although a successful product for Prentice, making th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modem
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by Modulation#Digital modulation methods, modulating one or more carrier wave signals to encode digital information, while the receiver Demodulation, demodulates the signal to recreate the original digital information. The goal is to produce a Signal (electronics), signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio. Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bit Per Second
In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time. The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s). The non-standard abbreviation bps is often used to replace the standard symbol bit/s, so that, for example, 1 Mbps is used to mean one million bits per second. In most computing and digital communication environments, one byte per second (symbol: B/s) corresponds to 8 bit/s. Prefixes When quantifying large or small bit rates, SI prefixes (also known as metric prefixes or decimal prefixes) are used, thus: Binary prefixes are sometimes used for bit rates. The International Standard ( IEC 80000-13) specifies different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bodging
Bodging (full name Chair-Bodgering) is a traditional woodturning craft, using Green woodworking, green (unseasoned) wood to make chair legs and other cylindrical parts of chairs. The work was done close to where a tree was felled. The itinerant craftsman who made the chair legs was known as a bodger or chair-bodger. History The term was once common around the furniture-making town of High Wycombe in Buckinghamshire, England. Traditionally, bodgers were highly skilled wood-turners, who worked in the beech woods of the Chiltern Hills. The term and trade also spread to Ireland and Scotland. Chairs were made and parts turned in all parts of the UK before the semi industrialised production of High Wycombe. As well recorded in Cotton the English Regional Chair. Although, originally the term was confined to High Wycombe, more recently since the revival of interest in pole lathe turning post 1980, many current chairmakers now call themselves bodgers. Bodgers also sold their waste prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBM Personal Computer XT
The IBM Personal Computer XT (model 5160, often shortened to PC/XT) is the second computer in the IBM Personal Computer line, released on March 8, 1983. Except for the addition of a built-in hard drive and extra expansion slots, it is very similar to the original IBM PC model 5150 from 1981. Name IBM did not specify an expanded form of "XT" on the machine, press releases, brochures or documentation, but some publications expanded the term as "''eXtended Technology''" or just "''eXTended''". Features The XT was regarded as an incremental improvement over the PC and a disappointment compared to the next-generation successor that some had anticipated. Compared to the original IBM PC, the XT has the following major differences: * The number of expansion slots is increased from five to eight * Base RAM is increased to at least 128 KB * 2x32KB ROM ICs replace the previous 6x8KB ROM ICs * A 10 MB hard drive is included as standard equipment * PC DOS 2.0 is included * The ...

Software Publishing Corporation
Software Publishing Corporation (SPC) was a Mountain View, California, Mountain View, California-based manufacturer of business software, originally well known for its "pfs:" series (and its subsequent "pfs:First" and "pfs:Professional" derivative series) of business software products, it was ultimately best known for its pioneering Harvard Graphics Graphics#Business, business and presentation program, presentation graphics program. Though SPC's earliest product was for the Apple II series, Apple II personal computer, most of its products were for use on Text-based (computing), text-based DOS desktop computers, with non-graphical user interface, graphical-user-interfaces (GUI), long before the graphical GUIs of Macintosh or Microsoft Windows existed. A salient benefit of Harvard Graphics, then, was that it brought sophisticated on-screen graphics capabilities to computers running the normally non-graphical, text-based DOS operating system. This factor played a role in the company' ... [...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 known as ECMA-48, ANSI X3.64 or ISO/IEC 6 ...

Zip Tone
In telephony, a zip tone (also known as a whisper tone or call waiting tone) is a call-progress tone which indicates a new incoming call is either connecting or waiting depending on the application. Unlike a ringtone, which alerts those near a telephone to answer it, a zip tone alerts someone already on the line—for example a telephone operator, call center agent, or telephone subscriber with call waiting service—that action is needed for an incoming call such as pressing a button or reciting a phrase (e.g. "May I help you?"). Tone composition and customization The tone is typically a single, short burst (e.g. 440 Hz for 5 ms) but can also be customized with multiple bursts or tones to hint at the nature of the call, so the agent can answer the call with the appropriate greeting; or a subscriber may know that a specific caller is calling or number was dialed (see distinctive ring). In some automatic call distribution applications the standard tone can be completely replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Call Waiting
Call waiting is a telephone service where a subscriber can accept a second incoming telephone call by placing an in-progress call on hold—and may also switch between calls. With some providers it can be combined with additional features such as conferencing, call forwarding, and caller ID. Call waiting is intended to alleviate the need to have more than one telephone line or number for voice communications. History Call waiting was introduced to North America in the early 1970s when the first generation of electronic switch machines built by Western Electric, Electronic Signaling System 1 started to replace older mechanical equipment in the old Bell System local telephone companies. At first, some smaller municipalities were able to offer customers call waiting only on a specific phone exchange (e.g., phone customers in Trenton, Michigan initially had to have a phone number starting with 671 to have call waiting, since 671 was at that time the only exchange in that area served ...

Escape Sequence
In computer science, an escape sequence is a combination of characters that has a meaning other than the literal characters contained therein; it is marked by one or more preceding (and possibly terminating) characters. Examples * In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. ** Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth translation phase. ** To represent the backslash character itself, \\ can be used, whereby the first backslash indicates an escape and the second specifies that a backslash is being escaped. ** A character may be escaped in multiple different ways. Assuming ASCII encoding, the escape sequences \x5c (hexadecimal), \\, \134 (octal) and \x5C all encode the same character: ...
