lnpdump(1) Lego Infrared Packet Monitor lnpdump(1)NAMElnpdump - Packet monitor for Lego infrared communication
SYNOPSISlnpdump [ options ]
DESCRIPTIONlnpdump 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.
