Perhaps. Terminal modes & speeds & special lines and so on set on the tty side can be seen on the pty side, although I think the pty is not notified immediately so it has to poll if it wants to detect terminal programs sending a BREAK signal and things like that.
I had a look at this about a year ago. I remember that a couple of small changes to the pty/tty layer would have been very handy to improve the quality of serial port emulation, and that might be the thing to do.
