Hi,
Just checked out why my pppd hangs on exit when the device is connected through USB and found out that the reason was that the code tried to change the linediscipline back to what it was before ppd and that the ioctl() hangs if the device doesn't exist any more as the USB device has disappeared at that point.
Shouldn't the ioctl(TIOCSETD) return a ENODEV instead of hanging ? The previous tcflush() does indeed do that and the problem was then avoidable, but I think I just fixed the symptoms, not the disease....
