According to a mail on your thumbgps list these are supported?

However, I just looked through the cp210x kernel module and I don't see 
*any* implementation of ioctl there at all?  Is the claim wrong or is 
this handled effectively at some higher level such as the ldisc?

Note there is a vendor cp210x driver which does contain an 
implementation of TIOCMIWAIT.  From eyeballing it, it looks 
straightforward in it's implementation (no idea why it's not in kernel?)
