Tandem Terminal Emulators (TTE)
Tandem Terminal Emulators (TTE). HP software product that includes several types of
terminal emulators that run on a PC with the Windows or OS/2 operating system. The
HP emulator in TTE provides a 65xx connection and IXF file transfer to a NonStop
system.
TCP. (Transmission Control Protocol) The Internet standard transport-level protocol that
provides the reliable, full-duplex stream service on which many application protocols
depend. TCP allows a process on one machine to send a stream of data to a process
on another. It is connection-oriented in the sense that before transmitting data,
participants must establish a connection. Software implementing TCP usually resides
on the operating system and uses the IP protocol to transmit information across the
Internet. It is possible to terminate (shut down) one direction of flow across a TCP
connection, leaving a one-way (simplex) connection. The Internet protocol suite is
often referred to as TCP/IP because TCP is one of the two most fundamental
protocols.
TDP. See Transaction Delivery Process (TDP).
TELNET. The Internet standard protocol for remote terminal connection service. TELNET
allows a user at one site to interact with remote timesharing systems at another site
just as though the user’s terminal were connected directly to the remote machine. That
is, the user invokes a TELNET application program that connects to a remote machine,
prompts for a User ID and password, and then passes keystrokes from the user’s
terminal to the remote machine and displays output from the remote machine on the
user’s terminal.
Telserv. HP product that provides the Telnet protocol for remote terminal connection
service.
TFTP (Trivial File Transfer Protocol). The Internet standard protocol for file transfer with
minimal capability and minimal overhead. TFTP depends only on the unreliable,
connectionless datagram delivery service (UDP), so it can be used on machines such
as diskless workstations that keep such software in ROM and use it to bootstrap
themselves.
TLAM. (Tandem LAN Access Method). The TLAM software provides an industry-standard
interface for accessing LANs from the NonStop system. Based on the IEEE 802.2
Logical Link Control standard, TLAM supports 802.2 Type 1 connectionless service as
well as the Multilan/NETBIOS protocol. With TLAM, you do not need to write
applications for a specific type of LAN.
Transaction Application Language. High-level language used to write systems software
and transaction-oriented applications.
Transaction Delivery Process (TDP). A host process that delivers and receives host
transactions by handling message routing for workstation sessions.
TTE. See HP Terminal Emulators.
