Hi, I've never used it with Rivendell, but I have done stuff with serial port triggers for advertising replacement on a webstream.
You can use the control lines which would normally be used by the modem to tell the computer its status using the the DCD (Carrier Detect), DSR (Data Set Ready), CTS (Clear to Send), and RI (Ring Indicate) lines. Normally in serial port use they are either +5v or 0v. What I have is a little program to monitor the status of each control line, when one of the status lines goes to +5V it runs one script, when that line goes back to 0V it runs another script. The way I have it, each script will switch the system from sending "live" audio or "pre-recorded audio" down the internet stream, it works well for online ad replacement. Normally you can pull a +5v from the data Set Ready line (pin 4 on the 9 pin port), you sometimes have to initialize the port to have the computer set the DSR ready line. So for example, to trigger the RI line to "on" you'd just jumper Pin 4 to Pin 9. The setup I have runs in Windows, however I'm sure this approach could be used with Rivendell. It would just be a matter of monitoring those 4 control lines.
