I assume you were referring to the dropping of DTR signal?
What would the odds be of getting ahold of the sources for the serial.device
and actually writing this in? I agree with you that it NEEDS to be in there,
because the open-close gig does NOTHING if someone else had the serial port
opened.
Suppose you had a few tasks up and running. One that was watching for dialins
on the serial port, and one that was calling out. The one calling out
wouldn't adversely affect the one waiting for calls by messing around with the
DTR, but the one waiting for calls would stop the dialout program from
dropping the DTR using open-close techniques.

It's not a bug, it's a feature! =^)
