   Hi!

   FreeBSD-1.1.5.1:

      Im  currently using a DCF-77  time  code reciever (Germany)  which is
   connected to sio01  (16550 UART).  It gets  its power from pin 4 (+/DTR)
   and pin 3 (-/TXD) of an 9 pin connector. The signal-line is pin 2 (RXD).
   I use the  dcfd that comes  with the xntpd  (../xntpd/parse/util/dcfd.c)
   package reading the time code with 50 baud from the device.

       Everything works  well except  sometimes  the sio-device changes its
   state  and the reciever  runs out of  power. After termination and a new
   start of the dcfd everything is o.k. again.

      Is this a feature/bug  of the device driver or  what can I do to stop
   this strange behavior? I use  /dev/cua01. With /dev/sio01 the dcfd don't
   work. 

   Thanks

   Lars
