Title: ser2net, Arduino, and microCore
Post by: Project23D on February 23, 2014, 10:58:04 PM

Seeing that using the search in this forum yields nothing for ser2net, I thought I would share the following:

to use ser2net, it's seems you must start is using the command: (perhaps I need to update my $PATH)
/usr/sbin/ser2net

But to add to that, the .conf file does not exist when you install ser2net, so you need to add one. Because I am new, and yet to learn how ideally to place files, I placed the .conf file here:
/home/tc

because what I'm doing with arduino needs to happen when the computer is booted, I updated bootlocal.sh with the following:
/usr/sbin/ser2net -c /home/tc/ser2net.conf

.filetool already saves the home folder, so I figured what better place to put the .conf file.

After that, I performed a backup, rebooted, and without SSH'ing back into the unit, I went into puTTY on my laptop and entered in the pertinents to the microCore box, and the output from the arduino was displayed. Awesome!

microCore is installed on a HP thin client with 128MB RAM, and even with all the junk I need, it only takes 70MB RAM with services running.

you can find the ser2net.conf examples on the net, but mine is just here and just one line:
2738:raw:0:/dev/ttyUSB0:9600

What version of Core are you running?
Where did you get ser2net?  Applications are supposed to install into /usr/local not /usr.

microCore 4.7.7

ser2net is in the repository, searched using tce-ab

after installing and trying to find where ser2net.conf file might be, (before I learned that I had to make it) I did:
sudo find / -name ser2net

gave the following output:
/tmp/tcloop/ser2net
/tmp/tcloop/ser2net/usr/sbin/ser2net
/usr/local/tce.installed/ser2net
/usr/sbin/ser2net

I didn't know what the other stuff really was for, and being an unorthodox Linux user, I just went with the /usr/sbin. Seemed right to me, ha.

Works great with what I wrote in the first post. I'm very excited that it worked first time.

I have microCore installed to the thin client's DOM, or Disk on Module, which is what HP calls the flash drive module with a laptop IDE connector on it. I am sure that some configs are obfuscated, but it works!

OK, I checked the 5.x repository and did not see it, that is why I asked.
I also run HP thin clients.
I have one T5720, four T5730 and one T5740.

unless ser2net is no longer supported in 5.x, or socat has taken it's place, please put ser2net in 5.x!

Hi Project23D
If you wish, you can try it under 5.x yourself. Boot up 5.x and fetch the extension:

Code: [Select]

cd /etc/sysconfig/tcedir/optional/
wget -c http://repo.tinycorelinux.net/4.x/x86/tcz/ser2net.tczLoad it and try it. It has no dependencies, so I suspect it will work. If you confirm it functions, it will be copied to the 5.x repo.

You can try it in 5.2, and if it works post a message in http://forum.tinycorelinux.net/index.php/topic,15906.0.html

ser2net works with 5.2!

now to figure out how to make it install it to load on boot...

The same way you make any other program install at boot.
