- * Test programm that implements a socket server which understands ASCII

- * < interface command ival_s ival_us can_id can_dlc [data]* >
- *
- * The commands are 'A'dd, 'U'pdate, 'D'elete and 'S'end.
- * e.g.
- *
- * Send the CAN frame 123#1122334455667788 every second on vcan1
- * < vcan1 A 1 0 123 8 11 22 33 44 55 66 77 88 >
- *
- * Send the CAN frame 123#1122334455667788 every 10 usecs on vcan1
- * < vcan1 A 0 10 123 8 11 22 33 44 55 66 77 88 >
- *
- * Send the CAN frame 123#42424242 every 20 msecs on vcan1
- * < vcan1 A 0 20000 123 4 42 42 42 42 >
- *
- * Update the CAN frame 123#42424242 with 123#112233 - no change of timers
- * < vcan1 U 0 0 123 3 11 22 33 >
- *
- * Delete the cyclic send job from above
- * < vcan1 D 0 0 123 0 >
- *
- * Send a single CAN frame without cyclic transmission
- * < can0 S 0 0 123 0 >
- *
- * When the socket is closed the cyclic transmissions are terminated.

CAN: major update for the Controller Area Network LTP tests This update for the LTP tests are dealing with CAN filters and the CAN frame flow down to the CAN netdevice and vice versa. The patch removes all the obsolete stuff from the source code directory that has been originally used to pick the tests from. The two new tools also reside in the SocketCAN SVN svn://svn.berlios.de/socketcan/trunk/test tst-filter: New filter test tool in *one* programm (easy to use & handle) tst-rcv-own-msgs: Checks the CAN frame flow inside the networking stack Additionally the virtual CAN driver needs to be loaded with a special commandline option to perform the CAN frame flow test correctly.
