Hi

I am trying to open port on windows 8.1

irb(main):001:0> require 'rubyserial' => true irb(main):002:0> ser1=Serial.new("COM1") RubySerial::Exception: ERROR_FILE_NOT_FOUND from C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/rubyserial-0.2.4/lib/rubyserial/windows.rb:10:in initialize' from (irb):2:innew' from (irb):2 from C:/Ruby22-x64/bin/irb:11:in `

'irb(main):003:0>

I have tried with this way also as mentioned in the below link

@nurdymuny the error message you've posted means that COM1 does not exist. You can find the list of COM ports by going to Control Panel->Device Manager->COM. That should give you the list of COM ports available on your system.

Yes , i am able to connect COM1.

Thanks

@nurdymuny you're able to connect to the serial port from a different program? Make sure that program does not have an active connection to the serial port when you run your ruby program. You should also check to see if your ruby program has the correct permissions to read from that serial port.
