I wrote a sloppy bit of code where I open a serial port and use it to do some basic modem communications.

Everything with it works great, but I can't manage to make it hang up the line. I'm guessing I need to drop DTR, but I'm not sure how I would do that using just a filehandle.

I've seen some complex examples using IO::File, but I'd rather not rewrite what I've got if there's a simple way to do it with what I have.

thanks!
