Ethernet.
Ethernet. A local area network (LAN) that uses the carrier sense multiple access with
collision detection (CSMA/CD) access method on a bus topology and is the basis for
the IEEE 802.3 standard.
FASTPTCP. The HP NonStop Kernel Spooler output driver.
file transfer protocol (FTP). A data communications protocol that is used for transferring
files between systems.
firmware. Firmware for AWAN 3886 units refers to the ROM firmware that is stored in non-
volatile RAM (NVRAM) on the unit and is not field-changeable.
flash memory. A semiconductor device that retains stored information whether power to the
unit is on or off. Information in flash memory can be overwritten with new information
when necessary.
gateway. Equipment that provides interconnection between two networks with different
communications protocols.
Gateway Access Protocol (GAP). A proprietary third-party product provided by Gemini
Communications, Inc., which supports non-standard asynchronous devices and
advanced asynchronous features for AWAN servers. GAP uses PORT AWAN ATAP.
gateway address. The Internet Protocol (IP) address of the entrance to the network.
HP NonStop TCP/IP subsystem. An HP subsystem that allows the use of Transmission
Control Protocol over Internet Protocol (TCP/IP) to access an HP host from Macintosh,
personal computer, and UNIX workstations.
HP Tandem Advanced Command Language (TACL). The user interface to the HP
Tandem NonStop Kernel operating system. The TACL product is both a command
interpreter and a command language. Users can write TACL programs that perform
complex tasks simply or provide a consistent user interface across independently
programmed applications.
HP Tandem Transparent Protocol (TTAP). A protocol by which TTAP printers use a
higher level flow control and, thus, do not use XON-XOFF or hardware flow control
(CTS).
initialization string. Several short commands that a computer sends to a modem. These
commands give the modem instructions to set it to a predetermined state.
Internet protocol (IP). A data communications protocol that handles the routing of data
through a network, which typically consists of many different subnetworks. IP is
connectionless; it routes data from a source address to a destination address.
Internet address. The 32-bit address assigned to hosts that want to participate in the
Internet using Transmission Control Protocol over Internet Protocol (TCP/IP). Internet
addresses are an abstraction of physical hardware addresses, just as the Internet is an
