    en.wikipedia.org/wiki/Uncapping

    Uncapping, in the context of cable modems, refers to a number of activities performed to alter an Internet service provider's modem settings. It is sometimes done for the sake of bandwidth (i.e. by buying a 512 kbit/s access modem and then altering it to 10 Mbit/s), pluggable interfaces (as by using more than one public ID), or any configurable options a DOCSIS modem can offer.

  5. Address decoder - Wikipedia

    en.wikipedia.org/wiki/Address_decoder

    An address decoder is a commonly used component in microelectronics that is used to select memory cells in randomly addressable memory devices. Such a memory cell consists of a fixed number of memory elements or bits. The address decoder is connected to an address bus and reads the address created there.

  6. Data Carrier Detect - Wikipedia

    en.wikipedia.org/wiki/Data_Carrier_Detect

    Frequent use of a serial port is for a direct computer-to-computer connection. This requires an adapter called a null modem, which isn't actually a modem in the traditional sense, but rather a connector plug that simply crosses the complementary pins on two serial ports so the two sides can communicate.

  7. Hayes AT command set - Wikipedia

    Terminal-emulator software typically allows the user to send Hayes commands directly to the modem, and to see the responses. In this example, the user of computer A makes the modem dial the phone number of modem B at phone number (212) 555-0100 (long distance). After every command and response, there is a carriage return sent to complete the ...

  8. Packet radio - Wikipedia

    en.wikipedia.org/wiki/Packet_radio

    A basic packet radio station consists of a computer or dumb terminal, a modem, and a transceiver with an antenna. Traditionally, the computer and modem are combined in one unit, the terminal node controller (TNC), with a dumb terminal (or terminal emulator) used to input and display data.

  9. Serial Line Internet Protocol - Wikipedia

    The compression algorithm used in CSLIP is known as Van Jacobson TCP/IP Header Compression. [5] CSLIP has no effect on the data payload of a packet and is independent of any compression by the serial line modem used for transmission. It reduces the Transmission Control Protocol (TCP) header from twenty bytes to seven bytes.
