<description>
<p>bidilink is a general purpose Unix tool for linking two
bidirectional data streams together. It extends the standard
Unix "filter" paradigma to bidrectional streams.</p>
<p>bidilink has support for several different drivers which may
be connected. You have to specify at least one, at most two of
them on the command line. If you specify just one driver the
second is automatically set to <opt>std:</opt>, which is the combination
of the process' STDIN and STDOUT.</p>
<p>Besides the order of initialization there is no difference in
specifying the stream specifications in a different order.</p>

<section name="Drivers">
<p><opt>std:</opt> The process STDIN and STDOUT pipes. If you
connect the <opt>std:</opt> driver with itself, strange things
may happen.</p>
<p><opt>exec:PROGRAM</opt> Fork off a process and use its STDIN
and STDOUT pipes.</p>
<p><opt>tty:DEVICE</opt> Open a TTY device (like
<opt>/dev/ttyS0</opt>). If you want to change TTY parameters
(like baudrate) do so by calling <manref name="stty"
section="1"/> previous to running bidilink.</p>
<p><opt>pty:[PTYSYMLINK]</opt> Open a pseudo TTY (PTY) as master
and create a symbolic link to the slave device. If you omit the
symlink path the name of the PTY slave is written to STDERR.</p>
<p><opt>tcp-client:HOSTNAME:PORT</opt> Connect a TCP socket to a
remote host.</p>
<p><opt>tcp-server:[IPADDRESS:]PORT</opt> Listen a local port and
wait for an incoming connection. You may specify an IP adress to
listen on. If you omit that the default of 0.0.0.0 is selected,
i.e. listen on all local IP adresses. This driver is limited to
a single connection. After an incoming connection was
established bidilink will close the listening port.</p>
<p><opt>unix-client:SOCKNAME</opt> Make a stream connection to a
local Unix socket.</p>
<p><opt>unix-server:SOCKNAME</opt> Listen on a local Unix
socket. This driver is limited to a single connection in the
same way as <opt>tcp-server:</opt></p>
