</div>Let me de-emphasise this.<br>
<br>
This was just an example for illustration, I don't know yet if this<br>
will work for you, as I'm waiting to see your response to Jerry.<br>
<br>
Taking your question as general, if you were testing this method, it<br>
would be better to do it in the Sugar Terminal activity than in the<br>
GNOME Terminal application, because you would next use the Sugar Frame<br>
to check the result. Having to switch from GNOME to Sugar would be<br>
time consuming.<br>
<br>
However, system commands entered into a shell would be effective from<br>
either GNOME Terminal application or the Sugar Terminal activity, or<br>
from other methods such as the text virtual console or an SSH session.<br>
<br>
How Sugar and GNOME work together: Sugar and GNOME are desktop<br>
environments <a href="http://en.wikipedia.org/wiki/Desktop_environment" target="_blank">http://en.wikipedia.org/wiki/Desktop_environment</a> and both<br>
are built on top of Linux operating system and kernel. GNOME also<br>
provides a middle level that Sugar uses. On the OLPC XO, you can<br>
switch between GNOME and Sugar desktop environments.<br>

<br>
</div>No, it is not the same.<br>
<br>
The sysfs is a tree of files beneath the /sys name, and is explained<br>
here: <a href="http://en.wikipedia.org/wiki/Sysfs" target="_blank">http://en.wikipedia.org/wiki/Sysfs</a><br>
<br>
In this thread context, sysfs is a method of controlling device<br>
drivers, in particular the device driver loaded when you connect the<br>
3G USB modem.<br>
<br>
On the other hand, the SysConfig file on the USB storage endpoint of<br>
your 3G USB modem is a file provided by the manufacturer or wireless<br>
service provider. I can't tell you what it is for, sorry.<br>
