Hi Robert,

you are right, CAN could be used there is nothing the would stop it
from working.  It is just like having a UART talking to the PC at 30
kbit/sec, possible yes. I was in deed referring to the standard
baudrates for CAN, all being very even numbers auch as 1Mbit, 500kbit,
250 kbit....  I would not know of a CAN network running at 115200 but
you are right in theory, not a problem, just need to find somebody
like another CAN node to talk to ;-)

Bob
