title: Do all serial ports start with COM?
body: <p>Pretty straight forward question. Do all COM ports (on Windows) start with COM (e.g. COM1, COM2, etc.)?</p>
  
  <p>Looking at tools like <code>com0com</code>, I see ports named CNCA1 and CNCB2. </p>
  
  <p>Could I have a COM port named anything (like a pipe)?</p>
