title: Why does Plink not behave the same as PuTTY with serial connection?
body: <p>I am trying to programmatically communicate with a device connected over a serial connection.  When I send commands using PuTTY, I have no problems.  But when I try to communicate using Plink, I get no response.  What would cause that difference?</p>
  
  <p>I connect to PuTTY through the command line using <code>putty -serial com3 -sercfg 9600</code> and then send my commands from within the PuTTY window using Ctrl-J (to adjust for the line endings, I think? It works in any case).</p>
  
  <p>And I connect to plink using <code>plink -serial com3 -sercfg 9600</code>, but then neither enter nor Ctrl-J or any combination seem to send my commands.</p>
