If you have trouble with these methods, then check out the SimpleFileAccess service. I have not tried it, but I am interested to know if it works.

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
