       ncpd - Daemon which handles the serial link to a Psion


       ncpd  [-V]  [-h]  [-v log-class] [-d] [-e] [-p [host:]port] [-s device]
       [-b baud-rate] [long-options]


       ncpd is the daemon which handles the serial  link  to  your  Psion.  It
       listens  at  port 7501 for local connections and provides basic PLP/NCP
       services for plpfuse and plpftp and other front-ends. It  auto-connects
       to  the psion, even after unplugging/switching off therefore it can run
       all the time if you can dedicate a serial device to it.


       -V, --version
              Display the version and exit

       -h, --help
              Display a short help text and exit.

       -e, --autoexit
              Exit automatically if the device is  disconnected.  Furthermore,
              use  the  current tty as I/O device. This option is intended for
              starting ncpd on demand using mgetty’s auto-detect function.  (A
              patch for mgetty is needed for that).

       -v, --verbose=log-class
              Increase  the  logging level of the program. the possible values
              for log-class are:

              nl     Set NCP debug level to LOG

              nd     Set NCP debug level to DEBUG

              ll     Set Link debug level to LOG

              ld     Set Link debug level to DEBUG

              pl     Set Packet debug level to LOG

              pd     Set Packet debug level to DEBUG

              ph     Set Packet debug level to HANDSHAKE

              m      Set overall debug level to verbose

              all    Turn on all the above logging on.

       -d, --dontfork
              Do not background the daemon.

       -p, --port=[host:]port
              Specify the port to listen on - by default  the  value  for  the
              host  is  and  the value for the port is looked up in
              /etc/services using the key  psion/tcp.   If  it  is  not  found
              there, a default value of 7501 is used.

       -s, --serial=device
              Specify  the serial device to use to connect to the Psion - this
              defaults to /dev/ttyS0

       -b, --baudrate=baud-rate
              Specify the baud rate to use for the serial connection.  If  the
              word  auto  is  specified,  ncpd  cycles  through  baud-rates of
              115200, 57600, 38400, 19200 and 9600 baud.  Default  setting  is


       plpfuse(8), plpprintd(8), plpftp(1), sisinstall(1)
