boolean waitfor($pattern [,$timeout])
# boolean waitfor ($string [, $timeout, $match_type])
# This method reads until a pattern or string is found in
+the input stream.
# All the characters before and including the match are re
+moved from the input stream.
This can be the error cause: waitfor removes all the text until the prompt, including the command output. No ideas how to work it out, though.
Sorry if my advice was wrong.
