TRAKKER Antares 2420 and 2425 Hand-Held Terminal User’s Manual
G-22
TCP
Transmission control protocol. This is the protocol for the transport layer in the TCP/IP
protocol. It provides a method for reliable, error-free, full-duplex communications
between sender and receiver nodes. TCP takes long messages from higher layers and
breaks them up before passing them to IP for transmission. TCP makes sure that the
messages are in sequence when it receives them, and it retries failed transmissions.
TE Configuration Menu
A menu-driven application that lets you configure 3270, 5250, or VT/ANSI terminal
emulation parameters. You can access the TE Configuration Menu at any time during a
terminal emulation session.
Telnet
The TCP/IP remote terminal protocol for connection to a login server.
terminal emulation (TE)
A device that is running terminal emulation looks like the terminal. For example, it uses
no CPU, no RAM, and no hard disk. Two general classifications are devices running in
Character mode and those running in Block mode. Character mode devices emulate VT
terminals where a character travels all the way from the host to a device and back. Block
mode devices emulate 3270 or 5250 terminals where entire screens are sent to a device,
the user fills in all the data fields on the device, and sends the entire screen back to the
host.
terminal IP address
Identifies the IP address assigned to the T2425. The IP address you set on the terminal
must match the address that is set on the DCS 300 or host.
TFTP
Trivial File Transfer Protocol. An abbreviated version of FTP that requires limited
interaction or instruction. Often used by devices without consoles to automate file
transfers of configuration data. TFTP allows file exchange between the terminal and
other network devices. Contrast with “FTP.”
TFTP server
Trivial File Transfer Protocol server. A server that uses TFTP for file transfer to and
from a remote system or device in situations when FTP may not be available (for
example, to transfer files in a TCP/IP direct connect network).
timeout
A defined time allowed for an event after which an alternate action is taken.
