Hi :)
You did the right thing by posting to this list first but your question is waaay beyond the skills 
of most people on this list.  

I think you need to copy&paste your question to the devs list and maybe ask your own distro's devs 
too.  It might be worth also asking in the general Gnu&Linux forum
because they can usually handle almost any distro.  

Errrr, it's worth letting people know which distro you are using and version number might help too. 
Good luck and happy hunting!
Regards from
Tom :)

Subject: [libreoffice-users] BASIC script how to read/write system files, like /dev/null in Linux
Date: Sunday, 14 October, 2012, 20:08

I am trying to write scripts accessing the system files, such as /dev/ttyS0.
If I use "Open" I got the error "Device I/O error" message. Are there any
special function call needed to be done for the system files? User
permission is good as I can access to the file using any other Linux

Following is the code I tried. It stalled on the first "Open" statement:

Sub Main
    Dim iNumber As Integer
    Dim aFile As String
    aFile = "/dev/ttyS0"
    iNumber = Freefile
    Open aFile For Output As #iNumber
    Print #iNumber, "*IDN?"
    close #iNumber
    iNumber = Freefile
    Open aFile For Input As #iNumber
    While not eof(iNumber)
        Line Input #iNumber, sLine
        If sLine <>"" then
            sMsg = sMsg & sLine & chr(13)
        end if
    Close #iNumber
    Msgbox sMsg
End Sub
