       lnpd - a LinuX Interface to the BrickOS Networking Protocol

SYNOPSIS

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

DESCRIPTION

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

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

       /usr/share/doc/lnpd/examples/lnptest.c
	      sample BrickOS code to be built and downloaded to your RCX. This code allows you to quickly ascertain that the lnpd daemon is  work-
	      ing with your RCX and lnpd installation.

       /bin/lnptest
	      a  simple  test  program which uses lnpd to communicate with the lnptest program downloaded into your RCX for testing with this pro-
