RS232 status lines, read with TIOCMGET.. [solved] :)

Some of you maybe saw my letter about the (4)tty ioctl "TIOCMGET int *state". The issue has been solved and the answer is that indeed the sio.c driver only reads the status line at opening. However a status line change will trigger a interrupt, and cause the driver to read status lines once more.
