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 interpreted.
-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 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 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.
