[squeak-dev] Serial port in linux

Ricardo Moran
Hi, I'm trying to use the Serial port to interface with an Arduino board. So far, I managed to make it work on Windows but I understand that Serial port on linux is a bit more complicated. I've read this old discussion http://www.nabble.com/communication-with-serial-port-t2549116.html and I am a little confused.
It says that John McIntosh made an EnhancedSerialPort plugin. Is it installed on the latest unix VMs?
It also says that Benjamin Schroeder wrote a SimpleSerialPort library. Which one should I use?

I've used the plugin which comes with vm and then just use SerialPort.
There are 2 things to look out for, you should start squeak with the '-notimer' option, otherwise most of the system calls will fail.
With the standard plugin you can only access /dev/ttyS[0-9], so if you want to use /dev/rfcomm0 for instance you can create a symlink to one of the unused /dev/ttyS[5-9].
If you follow those two it works pretty reliable.

Have fun,
Markus

It works!!!! Thank you very much! We were having this problem for a long time. Now we will be able to use Arduino on Linux (and also other projects that uses the SerialPort such as SqueakNxt). I am so happy! :D

Btw the very latest VM in svn has support for naming serial ports:

But there are some missing bits still needing to be integrated, details
on Mantis http://bugs.squeak.org/view.php?id=7266. The delay is entirely
my fault, I'm busy for a couple of days but should have provided some
[VM-team] guidance.

RSN,
Dave
