male serial port:
A serial port with pins
null modem:
An adapter that enables two RS-232 DTE devices to
communicate with each other without a regular modem or other DCE
device between them
page scan:
A mode in which a
Bluetooth
device analyzes pages by other
Bluetooth

9-pin connector
Serial Port Profile:
A serial communications service offered by a
Bluetooth
device, which must be implemented as defined by the
Bluetooth

Bluetooth
devices to interoperate in serial
communications, both devices must have this profile
service class:
The type of service that a
Bluetooth
device can provide to
other
Bluetooth
devices
stop bit:
In serial communications, where each bit of the message is
