NAME

rfcomm_sppd - RFCOMM Serial Port Profile daemon

SYNOPSIS

rfcomm_sppd [-bh] -a address -c channel [-t tty]

DESCRIPTION

The rfcomm_sppd utility is a Serial Port Profile daemon. It

opens RFCOMM
connection to the specified address server and channel.

Once connection
is established, the rfcomm_sppd utility provides access to

the server's
remote serial port via stdin/stdout or via pty(4) interface

if -t option
was specified.

The rfcomm_sppd utility opens both master and slave pseudo

terminals.
This is done to ensure that RFCOMM connection stays open un

til
rfcomm_sppd is terminated. The data received from the mas

ter pseudo terminal are sent over the RFCOMM connection. The data re

ceived from the
RFCOMM connection are written into master pseudo terminal.

The application in its turn opens the slave pseudo terminal and oper

ates 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.

RFCOMM channel could either be a number between 1 and 30 or a

service name.
Supported service names are: DUN (for DialUp Net

working service),
FAX (for Fax service), LAN (for LAN Access Using PPP

service) and
SP (for Serial Port service). If channel was not

specified then
rfcomm_sppd utility will try to obtain RFCOMM chan

nel for Serial
Port service 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.

FILES

/dev/pty[p-sP-S][0-9a-v] master pseudo terminals
/dev/tty[p-sP-S][0-9a-v] slave pseudo terminals

EXIT STATUS EXAMPLES

rfcomm_sppd -a 00:01:02:03:04:05 -c 1 -t /dev/ttyp1

Will start the rfcomm_sppd utility and open RFCOMM connec

tion to the
server at 00:01:02:03:04:05 and channel 1. Once the connec

tion has been
established, /dev/ttyp1 can be used to talk to the remote

serial port on
the server.
