How to read data from a serial monitor?

Also if you are reading another device over serial, e.g. a GPS receiver, you may want to use rfcomm1 instead of hci0 (rfcomm0). Depending on what device you are using, the method to read from a serial monitor varies. On an android device, you may take the node/javascript approach (this should work on all operating systems!).
