Looking for a Linux version of a RS232 to Telnet server like TCPCOM

In the land of windows there is a teriffic wee program called TCP-COM that lets you access your serial port or ports using a telnet socket. This is awesome for home automation & control, monitoring etc... But I wonder if anyone knows of a Linux program that can do the same thing?

Hi Bill,

I've used ser2net with good success. It's easy to set up and just works, at least for me. So far I've used it on a Ubuntu Feisty desktop and a Debian Sarge embedded ARM chip and had no trouble.

Some info: https://directory.fsf.org/ser2net.html

The man page: https://linux.die.net/man/8/ser2net

If you're running Debian, should get it installed for you.

Hm. It does occur to me that I don't think I've used ser2net to establish a connection from the serial port out through the network--just inbound (i.e. a remote client connects to a TCP port on my ARM box, which then sends the connection to a serial port). So that's the only behaviour I can vouch for.



Hope this helps,

Torben

Thanks I'll try it. I'm using Fedora Core 3

yum install ser2net

My fedora7 box found it in the main "fedora" repo ... probably the fedora-core repo on fc3

Hi there,

I have used this app with Linux

It will let you access a serial port via TCP, and it worked very well for me. Though, the GUI version for Linux is not available

If I'm understanding correctly, and all you want to do is read/write to the serial port from your own programmes, then all you need to do is open the device file and use it directly (if that's not what you're trying to do then I appologise in advance!).

On the command line you can do things like echo "foo" > /dev/ttyS0
This can be great for working with scripting languages like BASH script.
There is also a command for altering the port settings; can't quite remember, but it's called something like setty.

If you're writing in C (or any other language for that matter) you just do something like fd = open("/dev/ttyS0", O_RDWR)
You use ioctl() for changing the port settings.

Of course, you can also point a terminal emulator programme like minicom at the serial port and use it interactively.
