Subject: Help getting ruby-serialport to run in Windows XP

Dear All

I have not been able to make ruby-serialport in Windows XP.
http://ruby-serialport.rubyforge.org/
I have looked hard in the web and forums and have not been able to find
help, although i have found many people that have been equaly
unsuccesful.

It would be really great to have ruby-serialport work in Windows, it
already works well in linux and cygwin (at least for me)

I have succesfully compiled for windows following the excellent
instructions in:
http://blogs.law.harvard.edu/hoanga/2006/12/14/getting-a-ruby-c-extension-to-compile-on-windows/
It essential to read Part II)
http://blogs.law.harvard.edu/hoanga/2006/12/19/getting-a-ruby-c-extension-to-compile-on-windows-part-2/

However no matter what i do when running the miniterm.rb example the
program fails with:
(eval):3:in `create': No such file or directory (Errno::ENOENT)
        from (eval):3:in `new'
        from miniterm.rb:11

I have painfully tracked (I think) the problem down to this part of the
serialport.c code:

  rb_eval_string(
  "class SerialPort\n"

    "private_class_method(:create)\n"

    "def SerialPort::new(port, *params)\n"
      "sp = create(port)\n"    <============ BREAKS HERE
      "begin\n"
        "sp.set_modem_params(*params)\n"
             (...)

It would be great if someone more skilled could give me a hand with
this, I have reached the limits of my (also limited) knowledge.

Or even if someone could give me a compiled and working serialport.so
for windows XP would probably be good enough.

Thank you all
Eduardo
