Appendix C
Glossary
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:

.
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
