also, regarding the slave tty - I notice that if I do the following

% rfcomm_sppd -a phone -c dun -t ttyp9
% cu -l ttyp9

then it works fine, but if I exit cu and try again

% cu -l ttyp9

I get a "Device Busy" error.  I tracked this down to the fact that cu sets
TIOCEXCL but never unsets it.  While arguably cu should clean up after
itself, I wonder if you really do need to hold open the slave tty? If I
don't do that then it works as advertised and I can access the slave as
many times as I want with no problems..
