Does something like pty for windows?

Hi, all

   In my work, I often have to control applications running on

Unix servers from Windows through ssh. In order to be more effective,
I choosed to build some automation interactive script by ruby.

   I had tried Net::SSH, but I met some error like "cannot open /

dev/tty for read".

   So I turned to something like pty, but found the pty module

wasn’t supported in ruby on windows.

   Is there any workround?

Thanks
