Had you printed $line, you'd have seen something like
"+myscript:", not "Passwd: ".

As Peter said, if you don't provide with a pattern to look for,
zpty will look for NL characters.
That last zpty is probably still waiting because so far, it has
only received "Password: " and is waiting for a NL character
that will never come.
So, in your code above, you should wait for something more
specific than just ":":
zpty -r scppty line "assword: " || die "no password asked"
for instance.
