Hello,
I use a miniplex with two serial outputs.
When I put the baudrate on 4800 on the mux and in opencpn it works under w7 and ubuntu.
When I change to 57600 on the mux I can change under W7 and it works ok. When I start ubuntu I can change opencpn to 57600 but no input. When in terminal mode do : sudo stty -F /dev/ttyS1 57600 it works ok. But when I restart I have to initialize again.

How can I make this 57600 permanent.

Rein

In NavigatrixInsert the line you wanted (sudo stty -F /dev/ttyS1 57600) in the loop after Save and Exit. Next add stty to your sudoers file to make it automagic.

If you're on a LiveCD it would be and

At the moment I think it would be the same for a hard drive install. At the moment I don't have time to revert the machine because I've completely disable passwords and authentication on this machine and I have no backups, and I'd hate to lead you astray with bad advice and behaviour. If it doesn't I'll find a clean copy and we can go through editing sudoers.

Hello Moe,

I added the sentence as you said.

#!/bin/sh
AIS=/tmp/aisfifo
cd /
if ( ! pidof opencpn ); then
alsactl store -f ~/.config/alsa_std
alsactl restore -f ~/.config/alsa_ais
sudo stty -F /dev/ttyS1 57600
mkfifo $AIS
pidof gnuais || sudo gnuais -c /etc/gnuais.conf -f >/dev/null 2>&1
sed -i "s/^Locale=.*$/Locale=${LANGUAGE%%:*}/" ~/.opencpn/opencpn.conf
/usr/bin/opencpn $@ >/dev/null 2>&1
#/usr/bin/opencpn --verbose
sudo killall gnuais
rm $AIS
alsactl store -f ~/.config/alsa_ais
alsactl restore -f ~/.config/alsa_std
fi

I entered they other two commands.
Restarted the computer, but it was not working.
Tried to change baudrate by hand and got the following messag :

rein@rein-desktop:~$ sudo stty -F /dev/ttyS1 57600
>>> /etc/sudoers.d/00navigatrix: syntax error near line 2 <<<
sudo: parse error in /etc/sudoers.d/00navigatrix near line 2
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
rein@rein-desktop:~$

Tried to see what was in 00navigatrix but I couldn open it !
I am not so familiar with linux.

What went wrong ?

Rein

the file is all one line and looks like You're adding ", /bin/stty" on the end so when you launch OpenCPN the serial command you provided and placed in the script (opencpnais) can set the speed of the serial port without requiring a password.

Hello Moe,

I don't understand.
I type sudo ... and get the following answer.

rein@rein-desktop:~$ sudo medit /etc/sudoers.d/00navigatrix
>>> /etc/sudoers.d/00navigatrix: syntax error near line 2 <<<
sudo: parse error in /etc/sudoers.d/00navigatrix near line 2
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
rein@rein-desktop:~$

When I go to the /etc/sudoers.d/00navigatrix I need a password ?
I get a message ....... syntax error near line 2

How and what have I to correct in line 2 ?

rein

Some how there is extra data in the file /etc/sudoers.d/00navigatrix

The way to fix it is to replace it with a properly formatted file, but as you've noticed you can't open the file because this is one of the files that decides if you should have SUper powers, and it's buggered.

You'll need to boot from a LiveCD (USB), locate the file ((IT WILL BE ON YOUR HARD DRIVE AND NOT THE USB)).

Replace the file with the on that is in the LiveCD.

Copy the file /etc/sudoers.d/00navigatrix and overwrite the file /media/183742373_some_long_name_possibly/etc/sudoers.d/00navigatrix

Reboot

That will get you back on track.

If you're not on a hard drive installation simply boot into the menu, select "Options" and remake your persistence file.

I am not so familiar with linux.

I did not change opencpnais, but the other things I did.

When I did sudo medit /etc/sudoers.d/00navigatrix there is the message
syntax error near line 2

My idea is that there is a mistake already in opencpnais, but I don't know what ?

Sorry, I made a dreadful mess of the echo command, I'll be back.

root@glenda:~# echo ", /bin/stty" >> /etc/sudoers.d/00navigatrix

I'm sorry about the mistake, there is no -n in the command.

Another way to do the same thing is to Replace with this textSave and Exit.
Another,Replace all the text withSave and TEST the sudo command in another terminal to see that you didn't get any extra characters in the file. (It is all one line --without <newline> characters.)

If you did, revert the second file to what it was and try again.

Hello Moe,

- did a new installation on my hdu.

- made the changes you said, but still it is not working.

This is the result what I get, when I check the file it is the same as you said.

It worked.

At least the sudo part worked <<<wasn't fouled up.

The 'errors' you're seeing happen, they just do, and they do not signify anything important.

Everything in that text file /usr/local/bin/opencpnais is executed when you launch OpenCPN via Menu> Navigation> OpenCPN. If you launch OpenCPN via another method, the script is not used and the TTY change you suggested will not happen.

What happens when you enter in a fresh (just opened) terminal?

Are you asked for a password? If the sudoers file was changed you will not be asked for a password to change the TTY speed in a 'new' terminal.

When I start opencpn from the menu, I get input on ttyS0 (4800bd) but not on ttyS1 (57600bd).
When in terminal mode I type : sudo stty -F /dev/ttyS1 57600
then I get also input on S1 and I don't have to type a password.

I still have the problem that I have to set the baudrate by hand.
Everytime when I restart opencpn I want s0 on 4800 bd and S1 on 57600bd.

When I change the baudrate in opencpn, nothing happens.

What is the solution ?

I need to tap the brain trust...

Try this.

Open your autostart file.There isn't anything special about this file. It's just sitting there taking up a name and space. Lets put it to work.Add your commands that you claim work to the bottom of the fileSave and exit.
This file needs to be marked execuatableNow comes the magic part.

There is hardworking background application called cron which takes care of time (chronological) events. EnterThe first time you will need to select an editor. #2 (nano) is a good choice.

A little (nano) text editor opens. It is very basic. Don't freak out. All of the commands are listed at the botton of the terminal. The chronology table looks likeIt's _empty_ except for the comments (#). Add on a new line at the bottom of the file.This says, 'on every reboot, launch the following....',<ctrl><x>to Save and Exit.
You will be asked to varify this is what you want to do.

Reboot. It happens auto-magically.

Don't trust that it is being executed? Add to the bottom of ~/.config/autostart.sh and everytime you reboot, a file with the name YES_IT_IS_REALLY_WORKING will appear on your desktop.

Try it. Still not working? the sudo command should still be active from the last go-round. Check the stty commands.
