|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl bhS
|
|
.Fl a Ar address
|
|
.Fl c Ar channel
|
|
.Op Fl t Ar tty
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is a Serial Port Profile daemon.
|
|
It can operate in two modes: client and server.
|
|
.Pp
|
|
In client mode,
|
|
.Nm
|
|
opens RFCOMM connection to the specified
|
|
.Ar address
|
|
server and
|
|
.Ar channel .
|
|
Once connection is established, the
|
|
.Nm
|
|
utility provides access to the server's remote serial port via stdin/stdout
|
|
or via
|
|
.Xr pty 4
|
|
interface if
|
|
.Fl t
|
|
option was specified.
|
|
.Pp
|
|
If the
|
|
.Fl S
|
|
option is specified,
|
|
.Nm
|
|
will operate in server mode and act as RFCOMM server,
|
|
listening on
|
|
.Dv ANY
|
|
address and advertising a virtual serial port
|
|
via the
|
|
.Xr sdpd 8
|
|
daemon.
|
|
The
|
|
.Fl t
|
|
option must be specified;
|
|
the server side of the virtual serial port is attached to the pseudo-terminal
|
|
.Ar tty .
|
|
.Nm
|
|
should be run as root in order to communicate with
|
|
.Xr sdp 8
|
|
in this case.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility opens both master and slave pseudo terminals.
|
|
This is done to ensure that RFCOMM connection stays open until
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl a Ar address
|
|
In client mode,
|
|
this required option specifies the address of the remote RFCOMM server.
|
|
If this option is specified in server mode,
|
|
.Nm
|
|
will only accept connections from the
|
|
.Tn Bluetooth
|
|
device with address
|
|
.Ar address .
|
|
The address can be specified as BD_ADDR or name.
|
|
If name was specified then
|
|
.Nm
|
|
utility will attempt to resolve the name via
|
|
.Xr bt_gethostbyname 3 .
|
|
.It Fl b
|
|
Detach from the controlling terminal, i.e., run in background.
|
|
.It Fl c Ar channel
|
|
In both client and server mode,
|
|
this required option specifies the RFCOMM channel to connect to or listen on.
|
|
In server mode,
|
|
the channel should be a number between 1 and 30.
|
|
If not specified,
|
|
.Nm
|
|
will try to allocate RFCOMM channel number based on process ID.
|
|
In client mode,
|
|
the channel could either be a number between 1 and 30 or a service name.
|
|
Supported service names are:
|
|
.Cm DUN
|
|
(for DialUp Networking service),
|
|
.Cm FAX
|
|
(for Fax service),
|
|
.Cm LAN
|
|
(for LAN Access Using PPP service) and
|
|
.Cm SP
|
|
(for Serial Port service).
|
|
If channel was not specified then
|
|
.Nm
|
|
utility will try to obtain RFCOMM channel for Serial Port service via Service
|
|
Discovery Protocol from the server.
|
|
.It Fl h
|
|
Display usage message and exit.
|
|
.It Fl S
|
|
Server mode; see
|
|
.Sx DESCRIPTION .
|
|
.It Fl t Ar tty
|
|
Slave pseudo tty name.
|
|
If not set stdin/stdout will be used.
|
|
This option is required if
|
|
.Fl b
|
|
or
|
|
.Fl S
|
|
option was specified.

|
|
and channel

|
|
Once the connection has been established,
|
|
.Pa /dev/ttyp1
|
|
can be used to talk to the remote serial port on the server.
