docstring: This sets the terminal echo mode on or off. Note that anything the
          child sent before the echo will be lost, so you should be sure that
          your input buffer is empty before you call setecho(). For example, the
          following will work as expected::
  
              p = pexpect.spawn('cat') # Echo is on by default.
              p.sendline('1234') # We expect see this twice from the child...
              p.expect(['1234']) # ... once from the tty echo...
              p.expect(['1234']) # ... and again from cat itself.
              p.setecho(False) # Turn off tty echo
              p.sendline('abcd') # We will set this only once (echoed by cat).
              p.sendline('wxyz') # We will set this only once (echoed by cat)
              p.expect(['abcd'])
              p.expect(['wxyz'])
  
          The following WILL NOT WORK because the lines sent before the setecho
          will be lost::
  
              p = pexpect.spawn('cat')
              p.sendline('1234')
              p.setecho(False) # Turn off tty echo
              p.sendline('abcd') # We will set this only once (echoed by cat).
              p.sendline('wxyz') # We will set this only once (echoed by cat)
