I could offer you one of our M-CAN Boards. These Boards run NutOS. They 
are using the SJA1000 Controller as CAN controller. It is a easy task to 
log the can traffic and send it over a serial interface. There is only 
one limitation. CAN 2.0b can use up to 1 MBit Bitrates. Of course an 
RS232 Interface can not, so you have to user lowe CAN Bitrates.

Next week I'll experiment with the ATCAN128 as replacement of the 
ATMega128 for our can Boards, using Henkrik Maiers NutOS Port to the 
ATCAN128. It should work as well...

Best regards,

Ole Reinhardt
