- added error frame support in lib.c
- 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.
