@ericaslakson I see that you're on a windows machine 👍

As can be seen here, node-serialport is looking for Windows testers for the pull requests that add support for Node.js 4.

There are currently two pull requests for Node.js 4 support, #566 and #571.

#566 can be installed with npm install "git://github.com/ghostoy/node-serialport.git#nan1to2"

#571 can be installed with npm install "git://github.com/julianduque/node-serialport.git#master"

You could try either or both of them on Windows and report your findings 👍

@ericaslakson as fvdi said, Please try #566 and let us know how it goes in #578
