Appendix C Glossary - Socket RS-232 serial User Manual

acceptor: A Bluetooth device that accepts an action (e.g., a connection)
from another Bluetooth device, known as the initiator
AT command: The de facto standard language for controlling modems.
The AT command set was developed by Hayes and is recognized by
virtually all personal computer modems
authentication: Verification of identity as a security measure. Passwords
and digital signatures are forms of authentication
Bluetooth: Short-range, low power wireless technology used primarily for
cable replacement between devices. For more information about
Bluetooth and how it works, read Socket's technology briefs online at:
www.socketcom.com/support/learn.asp.
COM port: A serial communications port
CSA: Socket Cordless Serial Adapter with Bluetooth Wireless Technology
data bit: Bits that contain information, as opposed to bits used for starting,
stopping, or error checking
Data Communications Equipment (DCE): In serial communications, a
device between the communication endpoints that is responsible for
facilitating the communications process. A modem is the most common
kind of DCE
Data Terminal Equipment (DTE): In serial communications, a device at
the endpoint of the communications path. The CSA is a DTE. Other
examples of DTE are terminals, computers, protocol converters, and
multiplexors
Data Terminal Ready (DTR): A signal from a communications program
to a DCE, which indicates that the program is loaded and ready to run
device class: A parameter that indicates the type of device and which types
of services are supported. The class is reported during a device discovery
discoverable: Capable of being found by other Bluetooth devices during
the device discovery phase
encryption: The encoding of data to make it unreadable by unauthorized
users
female serial port: A serial port with pinholes
flow control: The control of transmission between communications
devices, to make sure the sender does not send data until the receiver is
ready to receive it
friendly name: A name you can assign to a Bluetooth device, e.g.,
"Lesley's Computer." If the Bluetooth device is discoverable, the friendly
name is provided to other Bluetooth devices during device discovery
gender changer: An adapter that changes a serial connector from male to
female, or vice versa
initiator: A Bluetooth device that initiates an action (e.g., a connection) to
another Bluetooth device, known as the acceptor
