Hi Brad, The latest version has the ability to use Serial port control lines as GPI's and GPO's. For each serial port on your system you've got 4 GPI's (DSR, CTS, CD, RI), and 2 GPO's (DTR, RTS) - using the control lines that used to be used primarily for modems.
Recently I set up a test system using these and once I'd figured out getting it up and running, it worked quite well (and considering many PC's still have serial ports, there was no additional cost). In the GPIP / Switcher setup, look for the Modem Lines option. Also you'll need to make sure that particular serial port is enabled and configured, and if you are using a Debian-based system (Debian, Ubuntu, etc) you'll need to add the logged in user to the dialout group.
