Is that really so? While testing a line discipline I have written myself (N_GIGASET_M101) I came to the opposite conclusion. Specifically, when I set the line discipline on eg. /dev/ttyS1 to N_GIGASET_M101 from the user space daemon I have written for that purpose, and that user space daemon exits, my line discipline is removed, ie. its .close method is called. That is true even if I kill the user space daemon by sending it an uncaught signal. -- Tilman Schmidt E-Mail: [EMAIL PROTECTED] Bonn, Germany Diese Nachricht besteht zu 100% aus wiederverwerteten Bits.
