Hi,
I'm having a strange problem with the transmission of my Arduino ProMicro MIDI interface on Ubuntu 11.10 (kernel 3.13).
It shows up as ttyacm0 in the system.
Every number "13" that I transmit which could be controller number "13" or a value like program change "13" comes in as number "10".
I suppose it is being recognized as a carriage return (13) which is being executed and then followed by a line feed (10) that actually gets transmitted to the [comport] object for some reason.
Does anybody have an idea how to fix this? Is there a ttyacm.conf (or similar) somewhere in the system that I could edit for a normal (non modem) behavior? Or can I set up the arduino to show up as a different device other than ttyacm?
On my other operating system everything is working fine with the same arduino and programming coming in as ttyacm0 - no special changes. Just another Ubuntu 11.10 with an older (original 2.6) kernel.
Thanks! Ingo

You might try to compare the output of 'stty -a -F /dev/ttyACM0' on both systems. It might be the newer Linux has a different idea about the terminal type of /dev/ttyACM0.

Thanks Jan!
I just did that but have no clue what these parameters mean or how to change them. I have already created a /etc/init/ttyACM0.conf but don't know how to enter any correct values.
Here are (only) the differences of the two outputs:
good midi in unit: bad midi in unit:
-cstopb cstopb -clocal clocal ixon -ixon ixoff -ixoff opost -opost isig -isig icanon -icanon -iexten iexten echo -echo echoe -echoe
If you (or anybody else) could give me a hint which of these settings might cause "13" to come out as "10" problem and how to change those settings I'd be extremely grateful!

OK, found it!
Using stty raw -F /dev/ttyACM0 did the trick! All numbers - incl. "13" are back as expected. Now I'll have to look at how to save it to disk ...
Thanks again, Jan for directing me to the right place!

Sooo ...,
setting it up to work correctly is no problem with stty anymore.
However, I cannot find out how to store my changed settings to disk. The -g or --store option does not save anything to disk. The console help doesn't tell me anything about storing those settings to disk.
Everytime I start up I have to set the ttyACM to raw by hand ...
Where are the files?

Your problem probably stems from the fact that the control characters like carriage return, etc are stripped since they are used for controlling the terminal in a terminal emulation mode. Back in the day, those characters were used to literally move carriage on a teletype machine. Most default terminal serial connections thus don’t transmit them since they are emulating this now lost functionality.
So setting the terminal connection to raw makes sense to me as it’s saying “pass ALL characters, even the old school terminal control characters”.
It took me about a week one time to figure out this was happening while working with a set of serial barcode scanners as it would drop bytes only *some times*. It turned out to be only when the bytes ended up including control character numbers, which were being stripped out. I ended up almost re-writing everything before finally figuring it out. Oh well.
