That's not why it doesn't work.  Read the doc for "zpty -r" again:

     If a PATTERN is given as well, output is read until the whole
     string read matches the PATTERN, even in the non-blocking case.

Note "the whole string".  This is why nslookup always has a "*" as the
first thing in the pattern when it calls "zpty -r".  So ...

  zpty -r telnet response $'(|*\n)telnet>'

... is probably more along the lines of what you want.

Same problem, I think.
