try is running as bellow.

C:\ruby\>ruby miniterm.rb COM3 9600 8 1  
(eval):1: (eval):1:in `private_class_method': undefined method`create’  
for clas  
s `Class' (NameError) from (eval):1 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`re  
quire’  
from miniterm.rb:1

While I’m not familiar with the mechanics of RubyGems, it appears that  
on at least several platforms its require() modifications are not  
compatible with this library [1]. The recommended fix is to load the  
library with the original require() method.

Kernel::require “serialport.so”

Since the library has not been updated since 2004, it is likely to  
become even less compatible with Ruby environments as they evolve. If  
anyone knows of any active alternate projects, I’d be very interested  
to hear about them. Good luck with your project!
