   Hi Foxidrive,   
      
   I too have 8+ years of RS232.  Started in the Military.  I   
   always found it a hoot and holler.   
      
   I was just looking for quick and dirty before I hook the thing   
   back up to the CNC machine.   If it did not work with   
   the quick and dirty, then the advanced stuff would have   
   started.   
      
   And, I knew I had used that stinking command before and   
   it drove me nuts that I forgot it.  Mumble, mumble.   
      
   -T   
      
   Putty seems to be overkill, but it will handle rs232.   
      
   CTL seems like a cool quick and dirty, but I am not about   
   to use Bing with all its spying.
