33.Nd RFCOMM Serial Port Profile daemon
34.Sh SYNOPSIS
35.Nm
36.Op Fl bh
37.Fl a Ar address
38.Fl c Ar channel
39.Op Fl t Ar tty
40.Sh DESCRIPTION
41The
42.Nm
43utility is a Serial Port Profile daemon.
44It opens RFCOMM connection to the specified
45.Ar address
46server and
47.Ar channel .
48Once connection is established, the
49.Nm
50utility provides access to the server's remote serial port via stdin/stdout
51or via
52.Xr pty 4
53interface if
54.Fl t
55option was specified.
56.Pp
57The
58.Nm
59utility opens both master and slave pseudo terminals.
60This is done to ensure that RFCOMM connection stays open until
61.Nm
62is terminated.
63The data received from the master pseudo terminal are sent over
64the RFCOMM connection.
65The data received from the RFCOMM connection are written
66into master pseudo terminal.
67The application in its turn opens the slave pseudo
68terminal and operates on it just like it would operate over the standard serial
69port.
70.Pp
71The options are as follows:
72.Bl -tag -width indent
73.It Fl a Ar address
74This required option specifies the address of the remote RFCOMM server.
75The address can be specified as BD_ADDR or name.
76If name was specified then the
77.Nm
78utility will attempt to resolve the name via
79.Xr bt_gethostbyname 3 .
80.It Fl b
81Detach from the controlling terminal, i.e., run in background.
82.It Fl c Ar channel
83This option specifies RFCOMM channel to connect to.
84RFCOMM channel could either be a number between 1 and 30 or a service name.
85Supported service names are:
86.Cm DUN
87(for DialUp Networking service),
88.Cm FAX
89(for Fax service),
90.Cm LAN
91(for LAN Access Using PPP service) and
92.Cm SP
93(for Serial Port service).
94If channel was not specified then
95.Nm
96utility will try to obtain RFCOMM channel for Serial Port service via Service
97Discovery Protocol from the server.
98.It Fl h
99Display usage message and exit.
100.It Fl t Ar tty
101Slave pseudo tty name.
102If not set stdin/stdout will be used.
103This option is required if
104.Fl b
105option was specified.

125Once the connection has been established,
126.Pa /dev/ttyp1
127can be used to talk to the remote serial port on the server.
