It /appears/ to be a "Bluetooth" serial port. Data written to this serial
port is transmitted via Bluetooth radio to a receiving Bluetooth device
(like your cellphone or your PDA). Data transmitted from outside Bluetooth
devices (again, like your cellphone or PDA) can be read from the serial
port.

It looks like the Linux kernel recognized the serial port, so you should be
able to use one of the Linux "Bluetooth management" suites to manipulate
the connection. Congratulations: you now have a way to sync your PDA or
phone with your Linux computer.
