I am having trouble with what seems to be a bug in the serial device.  What
I am doing is opening up the serial device a second time in shared mode while
someone is online.  I'm almost positive I am doing things correctly (only
one incarnation of the device is active at a time).  The problem is that about
1/10 times, dtr is dropped when the serial device is opened the second time.
I can get around this by forcing dtr, but I don't want to.

This is not just a problem with my software.  Every program that I have tried
that uses the serial device in shared mode does the same this.

Any solutions??
