Not sure because you have an older version of comport but it could be 
that COM10 is port 9 for your comport. Also it's telling you to create 
the comport with two arguments: try [comport 9 9600].
Better to use the version in cvs which lets you send a [devices( message 
to get a list of the actual serial ports. I can send you the dll if 
you're not into compiling.
