Oh - that's handy! I've been using my 'ttc' program to abstract out
the ttyUSB associated with a board, so I can just do something like:
'ttc panda console'. But my mappings would not break (as often?)
if I used the udev rules.
My excuse for not doing this earlier is that ttc precedes udev by
several years
Thanks.
