I can't event get serialport-0.6 working on any of my win32 COM ports. What I am experiencing is exactly what is outlined on http://rubyforge.org/tracker/index.php?func=detail&aid=560&group_id=61&atid=319 in terms of this library being nonfunctional on certain Windows platforms. Does anyone have a handle on this? Reading through past threads listed on c.l.r it appears as if for the past several years folks have had problems getting serialport to function using certain versions of Windows. And apparently it's not something related to a specific Ruby release version.
