Here are more details to the problem as described in this post.
(http://groups.google.com/
group/smslib/browse_thread/thread/4a866bfd6977785a/
0b7a71b685f17d7f#0b7a71b685f17d7f) - port switches.
And, even if I tell the program to get connect to the port (/dev/
ttyACM2) that it thinks the modem is connected to now, there are
problems.
Although it then can connect to the port, it is not able to receive
messages from it. When a message is received, it throws the following
error:
[smslib] : Running...
[smslib] : Running...
[smslib] : Running...

Exception in thread "Thread-3" java.io.IOException: Erro getting

After a while, it will try to restart the modem, but will fail because
the port now has already switched.
Here's log gotten from running 'dmesg' in Ubuntu:
