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
commands.
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
wend
Close #iNumber
Msgbox sMsg
End Sub
