lnpdump(1)		 Lego Infrared Packet Monitor		    lnpdump(1)

NAME
       lnpdump - Packet	monitor	for Lego infrared communication

SYNOPSIS
       lnpdump [ options ]

DESCRIPTION
       lnpdump is a packet monitor that	decodes	transmissions from Lego	bricks
       that are	equipped with an infrared transceiver. A lego  tower  must  be
       connected to the	PC for this program to work.

OPTIONS
       Below is	a summary of the lnpdump options:

       -a, --all
	      Dump data	of packets even	if they	are broken or cannot be	inter-
	      preted.

       -d DEVICE, --device=DEVICE
	      Set the device the Lego tower is connected to. If	this option is
	      not  present,  the device	name is	taken from the RCXTTY environ-
	      ment variable or the built-in default value in the given order.

       -f, --fast
	      Set the transmission speed to 4800 baud instead of 2400 baud.

       -h, --help
	      Show this	summary.

       -m N, --mask N
	      Set the host:port	bit mask value used to decode  LNP  addressing
	      layer  messages.	The default value is 0xf0 so that address 0x85
	      is decoded as 0x08:0x05 (host 8, port 5).

       -p, --noparity
	      Turn on legOS compatibility mode.	BrickOS/legOS Versions	before
	      0.2.5.2 used a slightly different	serial protocol	(no parity bit
	      instead of odd parity).

       -r, --raw (implies --all)
	      Dump all received	data, including	 keepalive  bytes  and	broken
	      packets. However,	bytes that form	a valid	package	are still dis-
	      playd as a block.

NOTES
       This program is based on	the lnphost library and	 should	 work  on  any
       posix  compilant	operating system. USB support is currently only	avail-
       able under Linux.
