       lnpd - a LinuX Interface to the BrickOS Networking Protocol


       lnpd [-emseconds] [-f] [-l] [-mnumber] [-n] [-pport] [-r] [-ttty_device] [-vlevel]


       lnpd  is  a  LinuX  daemon  that  allows multiple clients to connect to a LEGO RCX running
       Markus L. Noga's famous BrickOS (formerly legOS) operating system  and  exchange  messages
       using the LNP protocol.


       A summary of options understood by lnpd

       -d     Don't go into background

              Extra wait time for lnp

              Run LNP at 4800 baud

              Enable logging to syslog or file
              NOTE: filename of '-' means to log to stdout.

              Set max number of lnpd clients (default 16).

              Do not manage tty lockfiles.

              Daemon should listen on port {TCP_Port}. Default is port 7776.

              Run daemon in realtime mode.

              Use {tty_device}. Defaults to /dev/ttyS0.

              Enable enhanced logging. Valid levels are: d, l, i, a, and c.

       -h     Show similar help text at command-line.

       -u     Show short usage message.

              Display lnpd version

              Mandatory  or  option  arguments to long options are also mandatory or optional for
              any corresponding short options.


              The default device for lnpd. (Also See -t: in OPTIONS, above).

              sample BrickOS code to be built and downloaded to your RCX. This code allows you to
              quickly  ascertain  that  the  lnpd  daemon  is  working  with  your  RCX  and lnpd

              a simple test program which uses lnpd  to  communicate  with  the  lnptest  program
              downloaded into your RCX for testing with this program.


       You'll find additional documentation in /usr/share/doc/lnpd (on Debian GNU/Linux systems)
