.Nd RFCOMM Serial Port Profile daemon
.Sh SYNOPSIS
.Nm
.Op Fl bhtS
.Fl a Ar address
.Fl c Ar channel
.Op Fl t Ar tty
.Sh DESCRIPTION
The
.Nm

.Nm
utility provides access to the server's remote serial port via stdin/stdout
or via
.Xr pts 4
interface if
.Fl t
option was specified.

If
.Fl t
options was specified,
the server side of the virtual serial port is attached to a pseudo-terminal.
.Ar tty .
Otherwise the virtual serial port is attached to the stdin/stdout.
.Nm
should be run as root in order to communicate with

.It Fl S
Server mode; see
.Sx DESCRIPTION .
.It Fl t
Use slave pseudo tty.
If not set stdin/stdout will be used.
This option is required if
.Fl b
option was specified.
