Don't most interfaces just block until there's something to read? With this line of code:while true:s = serialport.readlinewhich is run on the pi with the python script. A serial connection is between the pi and a desktop.

As I type characters on the terminal (Putty) on the desktop, there should be an interrupt to say data is ready or a flag maybe. I dont want always listen to the serial port (Polling).

I dont want always listen to the serial port (Polling).Start a thread that waits on a read of the serial port.

The database part is easy but I've never worked with serial collection.Hi Bobby,There's a module for handling the serial port called PySerial:Does this look useful for you? You could set up a thread to read datafrom each of your those ports, and just call read.There does appear to be work on making PySerial asynchronous:but I don't know how far this has gone yet; you may want to talk with theTwisted folks for an up-to-date status on it.Best of wishes!.
