Jerry, or anyone else for that matter,...
I'm trying, mostly for the sake of learning, to write a simple multi-threaded
comm class.  Most of it seems to work, so far, except the queues.  I'd like
to have a write queue and read queue.  That seems simple - there's a deque in
the STL.  Except that it doesn't really want to work if I make it volatile. 
If it is volatile, the compiler complains.  If it isn't volatile, it becomes
really funny - I write to the serial port fine, but reading doesn't always
seem to work... if I don't give it a long enough delay, the "AT" coming back
from the modem (which I see in a line monitor) only is discovered if I give
it a long enough timeout.  I'm sure volatile would help here - if I could
figure out what I was doing with it.  :-)
Leaving it non-volatile and then removing the thread/queue for reading may
work.  However, I'm suspicious that the write queue may not work in stress
situations (i.e., trying to send a file).
Any ideas?
