If my ppp connection drops (due to phone line disconnect) I cannot anymore use /dev/ttyS1 (e.g. for reconnecting ppp).
Any attempt to touch the device will hand, like stty -a </dev/ttsY1 never starts (ps shows bash still owns the process). If I shut down ppp properly then I have no problem reusing the device. -- Eyal Lebedinsky ([EMAIL PROTECTED])
