[u]I'm looking for an understandable clear explanation of what goes on when a serial connection is opened.[/u]
I have a chip producing output on /dev/ttyusb4 and when I open a serial terminal there comes the data as expected. If I change the port to ttyUSB3 I will see the data coming from the mobile modem through which I connect.
Alex at insidegadgets.com used VUSB in his Standalone Voltage and Temperature Logger and this works in such a way that when I have an application like a spreadsheet open the data comes into the spreadsheet automatically.
A site I posted recently uses a python module to prepare and receive serial data and that is sent to a web page .
So whats happening ? What can I do to put the serial data coming in into a spreadsheet automatically?
