Just replace the address and port information. Also, you may be using a different serial port (i.e. change the <code>/dev/ttyS0</code> part).

I stumbled upon this question via a Google search for a very similar one (using the serial port on a server from a Linux client over TCP/IP), so, even though this is not an answer to exact original question, some of the code might be useful to the original poster, I think:

All the tools you would need are already available to you on most modern distributions of Linux.

As several have pointed out you can pipe the serial data through netcat. However you would need to relaunch a new instance each time there is a connection. In order to have this persist between connections you can create a xinetd service using the following configuration:

<pre><code>service testservice
{
 port = 5900
 socket_type = stream
 protocol = tcp
 wait = yes
 user = root
 server = /usr/bin/netcat
 server_args = "-l 5900 &lt; /dev/ttyS0"
}
</code></pre>

Be sure to change the <code>/dev/ttyS0</code> to match the serial device you are attempting to interface with.

Open a port in your server with netcat and start listening:

<pre><code>nc -lvp port number
</code></pre>

And on the machine you are reading the serial port, send it with netcat as root:

<pre><code>nc &lt;IP address&gt; portnumber &lt; /dev/ttyACM0
</code></pre>

If you want to store the data on the server you can redirect the data to a text file.

First create a file where you are saving the data:

<pre><code>touch data.txt
</code></pre>

And then start saving data

<pre><code>nc -lvp port number &gt; data.txt
</code></pre>

I have been struggling with the problem for a few days now.

The problem for me originated with <a href="http://en.wikipedia.org/wiki/VirtualBox" rel="nofollow noreferrer">VirtualBox</a>/Ubuntu. I have lots of USB serial ports on my machine. When I tried to assign one of them to the VM it clobbered all of them - i.e. the host and other VMs were no longer able to use their USB serial devices.

My solution is to set up a stand-alone serial server on a netbook I happen to have in the closet.

I tried ser2net and it worked to put the serial port on the wire, but remtty did not work. I need to get the port as a tty on the VM.

socat worked perfectly.

I think your question isn't quite clear. There are several answers here on how to catch the data coming into a Linux's serial port, but perhaps your problem is the other way around?

If you need to catch the data coming out of a Linux's serial port and send it to a server, there are several little hardware gizmos that can do this, starting with the simple serial print server such as this <a href="http://www.lantronix.com/device-networking/external-device-servers/mss100.html" rel="nofollow noreferrer">Lantronix gizmo</a>.

No, I'm not affiliated with Lantronix in any way.
