RFCOMM_SPPD (1) | General commands | Unix Manual Pages | :man▋

The rfcomm_sppd utility opens both master and slave pseudo terminals. This is done to ensure that RFCOMM connection stays open until rfcomm_sppd is terminated. The data received from the master pseudo terminal are sent over the RFCOMM connection. The data received from the RFCOMM connection are written into master pseudo terminal. The application in its turn opens the slave pseudo terminal and operates on it just like it would operate over the standard serial port.

The options are as follows:

-a address
This required option specifies the address of the remote RFCOMM server. The address can be specified as BD_ADDR or name. If name was specified then the rfcomm_sppd utility will attempt to resolve the name via bt_gethostbyname(3).

-b Detach from the controlling terminal, i.e., run in background.

-c channel
This option specifies RFCOMM channel to connect to. The channel must provide Serial Port service. If channel was not specified then rfcomm_sppd utility will try to obtain RFCOMM channel via Service Discovery Protocol from the server.

-h Display usage message and exit.

-t tty Slave pseudo tty name. If not set stdin/stdout will be used. This option is required if -b option was specified.
