sockets.
can-dump prints data flowing on CAN bus.
Usage of can-dump:
sh> can-dump [options] <CAN interface>
(use CTRL-C to terminate can-dump)
Examples:
can-dump vcan0
$> can-dump vcan0

can-send sends data on the CAN bus.
Usage of can-send:
sh> can-send [options] <CAN interface> <CAN frame>
where <CAN frame> is of the form: <ID-hex>#<frame data-hex>.
Examples:
can-send vcan0 f12#1122334455667788
can-send vcan0 ffa#deadbeef
$> can-dump vcan0 &
$> can-send vcan0 f12#1122334455667788
vcan0 712 00000000 11 22 33 44 55 66 77 88 |."3DUFW.|
$> can-send vcan0 ffa#deadbeef
