Hi, <div><br></div><div>I use named serial ports on Linux all the time and I didn't have any problem. I think the latest release has the serial plugin fix but I can't confirm because I usually use my own vm (which the vm guys gladly helped me compile :) ). If it's of any help to you, you can download it from here: <a href="http://tecnodacta.com.ar/gira/Arduino.10%20(linux%20only).zip">http://tecnodacta.com.ar/gira/Arduino.10 (linux only).zip</a> and test it.</div>

If you have some experience with serial I/O on Linux, I would appreciate your giving it a quick shakedown; if it is just plain broken or is still known to work, it would be nice to confirm either way. I would like to use the binary distribution, but it does not report enough of what it is trying to do (so no clues when things fail) and I end up hacking to add tracing with possible installation troubles as a result.<br>
<br>
That said, this time around, I find myself in serialPortOpenByName() and puzzled by the failure being allegedly detected by:<br>
<br>
/* save the old state */<br>
if (tcgetattr(sp->spDescriptor, &sp->spTermios))<br>
<br>
My question: is there old state to save on the first pass? errno is not helpful; it is set to 5 aka I/O error :( I find myself wondering whether this should be conditional on the internal state of the descriptor, and the failure to open simply being that it gives up too easily? Then again, it could be detecting a true error condition and preventing certain disaster in the lines that would follow.<br>
<br>
Any ideas? I can't get /dev/ttyS0 to open by name or number. 'COM1' worked nicely on Windows.<br>

Hi Bill,<br>
<br>
haven't used the serial interface with the new VMs (yet), but previously under<br>
Linux I had to use the vm option '-notimer'. I did not find any negative side<br>
effects with that option.<br>
<br>
Hope this helps,<br>
