Hi Marcos,<br>
<br>
I don't know of any Modbus implementations.  I proposed developing a
native Smalltalk implementation for this year's GSoC [1] but it didn't
get selected as a priority.  I am still interested in developing one so
I am curious as to your application.  The other option would be
interfacing to an existing C library using NativeBoost (but I haven't
had any experience with that yet.)<br>

Do you have some problem setting a proper 'Subject' and also leaving

Hi, thanks so much for your promptly support.
It worked!!!.

I was doing

FileDirectory deleteFileNamed: 'c:\temp\prueba.txt'.  and get an error.

But then I tryied

FileDirectory default deleteFileNamed: 'c:\temp\prueba.txt'.  and it
worked.

Sorry I missed include default

Again, thank so much.

This is the first time I wrote.

I am trying to use Seaside to work with Web Services that provide a
Xerox Multifunction Device. I will tell you how everything is going
on, If there is anay doubt I will tell you.

Best Regards

Marcos.

Hi,

I'm developing a mod for Scratch that will allow controlling an
educational
robot via Bluetooth. I'm using SerialPort2 class that is included in
Scratch
plugin and allows opening ports by name. Everything works fine BUT, when
I
send commands in a loop, and the connection is lost (i.e. the robot was
powered off), the VM freezes. I tried forking the port nextPutAll like
that:

timer := Delay forMilliseconds: 1000.
port := SerialPort2  new.
port openPortNamed:'COM14' baud:57600.
process := [port nextPutAll:'test'. Transcript show:'port'.] forkAt: 1.
[timer wait. Transcript show:'delay'. process terminate.] forkAt: 7.

but with no result. Is there any way to write to a serial port with
timeout?

Well, at first I tried using larger numbers, but it seems, that my VM
has maximum priority equal to 8. Processor userBackgroundPriority
prints 3 and Processor userInterruptPriority prints 5.

      <pre wrap="">hi Marcos,

Welcome.  I hope you are having fun with it.  First, I've updated the
subject to be more specific.  That makes it easier for us to track.
Hope that is okay.
A few queries then to narrow down the scope of your query..

You say 'windows' but use all lower case.
Do you mean 'Windows' as in Microsoft Windows?
Also which version?

By 'system directory', do you mean 'C:\Windows\System' or
'C:\Windows\System32' or some other protected directory?

You imply that you already know how to delete a file outside the system
directory. What is the code you used that was successful for that, which
fails with a system directory?

What things have you tried already?
* Can you delete the required file outside of Seaside, just Pharo 1.3 ?
* Can you delete the required file outside of Pharo 1.3, from Windows
Explorer, and from the command-line ?

btw, You may find the following of interest...
<a class="moz-txt-link-freetext" href="http://www.catb.org/esr/faqs/smart-questions.html">http://www.catb.org/esr/faqs/smart-questions.html</a>

I'm not an expert, but with answers to those questions I hope I'll be
able to help you.

cheers -ben
