FILES

       /dev/ttyS0
              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 working 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 program.
