As pointed out by Andre Naujoks the pseudo random generator should be
initialized with a seed to prevend this ugly behaviour:
$ ./cangen vcan2 -v & ./cangen vcan1 -v
[1] 5995
vcan2 567#69.98.3C.64.73.48
vcan1 567#69.98.3C.64.73.48
vcan2 451#4A.94.E8.2A.EC.58.55.62
vcan1 451#4A.94.E8.2A.EC.58.55.62
vcan2 729#BA.58.1B.3D.AB.D7.7E.50
vcan1 729#BA.58.1B.3D.AB.D7.7E.50

- added sprint_* functions for CAN-frame output in lib.c / lib.h
- added comments / cosmetics
candump.c:
- removed support for the output in ASC representation (moved to log2asc.c)
- added option '-l' for logfile creation e.g. 'candump-2007-01-01_164123.log'
- added funtionality to terminate candump by pressing [ENTER] (not only ^C)
- added error frame support
- added color support even when reading from 'any'
- three different color levels (e.g. -c -c -c)
- making use if lib.c
cangen.c:
- CAN frames generator for testing purposes (e.g. on vcanx)
(nice when you're on vacancy at the baltic sea and have no real CAN source :)
log2long.c:
- convert compact CAN frame representation into user readable representation
log2asc.c:
- convert compact CAN frame logfile to ASC logfile for 3rd party CAN tools
Next step: Create a tool to replay candump logfiles.
