Subject: How do I use IO.ioctl(arg1, arg2..)

Hi

The pickaxe book is a bit sparse on documentation for using the method
ioctl for IO class objects.

Is there a guide somewhere?

I want to turn echo on and off on an IO object.

I guess I could use system("stty -F /dev/ttyS1 echo"), if I knew which
physical device was inside a particular IO object.

Thanks for your time (and Ruby too)
