I am going to be using the arduino duemilanove to provide a smart interface for a project I am working on. One of the actions which the arduino needs to be able to trigger is a computer program that performs an action when the RI pin on the com port is triggered. Is there any way, using the FTDI virtual com port, that I can make this happen?
In other words, a user presses a button which is connected to an arduino input. The arduino then triggers a ring indicator on the com port, thus starting the software.
In lieu of the RI, I can also trigger using DCD, DSR, or CTS on the com port, but I can NOT trigger by simply sending data over the port.
Your help is appreciated!
