[Ovmsdev] Can bus error while read canbus

[Michael Geddes]

Ahh.. yes.

I've had a look and I believe I've got it. I'll just need to make sure that
the "can can? listen" and "can can? active"  commands go through the
poller so that it starts up the polling thread (with a bit of conditional
compilation for the where the poller is not compiled in).

I'm assuming that you do, in fact, call these commands?

On a side note, I've been working on a whole bunch of stuff to allow users
to program a whole vehicle implementation with duktape and commands... so
if somebody were interested in testing that (the bit that I'm struggling to
find time for at the moment) I'd be happy for the help.
