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  con-
     nected 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 environment  vari-
	    able 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 in-
	    stead of odd parity).

     -r, --raw (implies --all)
	    Dump all received data, including keepalive bytes and  broken  pack-
	    ets.  However, bytes that form a valid package are still displayd 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 available under
     Linux.
