NAME
lnptest - LNP Client Test Application SYNOPSIS
lnptest DESCRIPTION
lnptest is an LNP Daemon test client used to test the connection between lnptest and the LNP daemon through the Ir Tower to a corresponding test program running in an RCX. See the FILES section for the location of the RCX test program source code (distributed with this pack- age). OPTIONS
lnptest does not support command-line options. USAGE
To run the test: - compile the lnptest.c RCX program - start the lnpd daemon - download the lnptest.lx program to the RCX - (at the RCX) run the program just downloaded to the RCX - run this lnptest program - inspect the output looking for lack of failure messages FILES
/usr/share/doc/lnpd/examples/rcx In this directory is the source to the RCX-side program which is called lnptest.c but written to be compiled against BrickOS. SEE ALSO
lnptest2(1), lnpdll(1), lnpd(8) You can find additional documentation in /usr/share/doc/lnpd (on Debian GNU/Linux systems) AUTHOR
