I am not familiar with plink, so I cannot help you. I recommend using
an SSH module which help a lot with all of this. That being said, maybe this
post will help:
http://code.activestate.com/lists/python-tutor/74807/
Also take a look at the subprocess.communicate documentation[1] as
it says
""" Interact with process: Send data to stdin. Read data from stdout and
stderr, until end-of-file is reached. **Wait for process to terminate**. The
optional input argument should be a string to be sent to the child process, or
None, if no data should be sent to the child.
communicate() returns a tuple (stdoutdata, stderrdata).
Note that if you want to send data to the process's stdin, you need to create
the Popen object with stdin=PIPE. Similarly, to get anything other than None in
the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.
""" (emphasis added)
This suggests communicate is waiting for the plink to end? Also, you
should probably pass in a pipe so that you can send data more than
once. Note, I am not familiar with subprocess so YMMV.
