- void Disconnect(string device)
-
- Disconnect a RFCOMM TTY device that has been
- created by Connect method.
-
- To abort a connection attempt in case of errors or
- timeouts in the client it is fine to call this method.
-
- In that case one of patterns of the Connect method should
- be supplied instead of the TTY device.
