Importing values in real time to text image

datsyuk
Hello,

I was wondering if it's possible to continuously update a text image file with data values coming from a serial port.  Right now I'm running a script that saves the data values to a text file.  Ideally, I would like to send the data values to a text image in real-time and then use the live histogram plugin to get a live histogram.  It's a similar concept to the live histogram plugin currently available but instead of using intensity values from an image, I'm using data values obtained through a serial port.  

Alternative approaches would be appreciated as well.

Thanks,
