Hi everyone,
Sorry for the long time response but here is the patch, I think this way should
work, if anyone has any suggestion let me know. What I do now is, in case I
don't have the tty available I reschedule the work, I have tried it and it
works with no problem, I even tried removing the device, and didn't find
anything strange.
