Alternatively you might want to set the pty to raw mode, which disables 
character translation and gives a more pipe-like semantics.  The latest 
IO-Tty v1.00 has a set_raw() method...

I'll second that. :-)

Ugh, I just released a much-improved version of IO-Tty (v1.00), please 
take a look how it's done nowadays (in the 'try' and 'test.pl' 
scripts).  Alternatively try using Expect, which gives you similar 
functionality to waitfor() and also lets you use an already opened 
filehandle.

Hope this helps,

Roland
