Hi Remzi,
thank you for your post, there must be some work around on this script,
because the gnome-terminal, which I'm using as the interface,
has change its options in a later version,
so some of my commands nowadays do not work or bring an error,
so maybe I will work with another terminal, maybe lxterminal,
but this is just one script, which works together with:
tapclean and audiotap(using the text command version tap2audio and audio2tap)
will make a change when I try to use it under my Raspberry,
there is it where I want to use it mainly!
Or maybe some other has ideas to change it and uploads his version here....
