Curious... anyone play with JS for RS232 send/receive?

[Jared Kuroiwa]

Just got a call from a friend that wanted something to a medical control device using RS232 and I figured why not try and do it with a browser instead of something compiled. I've seen a few implementations of Node.js for Arduino projects through USB and figure it can't be that different, right?

Any pointers?

Thanks in advance!

Is there such a thing as a browser-side node.js implementation?

Are you thinking about having the interface in the browser, and it sends the requests back to a server that controls the hardware, or having the browser communicate directly with the serial port?  AFAIK, there's no way to do the latter...at least without something like a Java Applet.

Direct control of the serial port...

If anything it would be an interesting project to play with...

That code for node runs on the server side though, not in the browser--the browser js code just makes ajax requests back to the server.  JS code running in browser wouldn't be able to read/write to a serial port.

Either way, sounds like an interesting project.  Can I ask what type of device you're trying to communicate with?

It's a syringe pump.

I've attached the manual for it.

Thanks,
