I have a device that sends data across a traditional serial line (9600 8N1). I'd like to receive this data on a Chromebook inside a webpage that contains a set of textboxes. I will take care of parsing the data and populating the textboxes. I need you to get the data from the device to my page.
Ideally, the user will install a private Chrome App and/or Extension which will open the first available serial port and then just sit there, awaiting a signal. My page will, I assume, register some kind of listener. Once data is received, the entire message will be read and passed to a script on my page, where I will parse the data and put each value in the right element on the page.
For now, see the attached page as a basic sample. I want you to move data from a serial device and have it show up in my textarea element.
The serial connection is unidirectional. The device just pushes the data to the Chromebook, there is no data sent back. I'm using a serial DB9 to USB connector to attach the device to my Chromebook.
