There are portable ways of doing this without invoking a separate program. There
are a couple of Posix calls to do this. The easiest way of finding out how to do
this is to look up the metods in various Perl FAQs. That is where I found the
answer to it last time I looked (or was it the Perl book).

Use the Posix interface so that context can be saved and restored easily without
depending on the arcane syntax of stty.
