I don't know if anyone ever got back to you with a fix, but for me the

fix was really simple.

 

I just added a self.sendline() and a time.sleep(0.5) right before the

first read_nonblocking() call within synch_original_prompt

 

The reason is that you have to have stuff in the buffer in order to

read it. In the case that they programmed for originally,

**something** exists in their prompt (probably a space) after the $ or

#. In my case (and probably yours) the last thing on the prompt

**is** the $ or #, causing the buffer to be non-existent when the

first read_nonblocking() happens. So all we do is put something there

before the read.

 

Why not just get rid of the first read since it is just "clearing the

buffer" anyway? Because then, although it would now work for us, it

would no longer work for the original programmers.
