Finally, just checking, you DO have the full path name to the "TTL Device" in your "Serial port setup" as in "/dev/ttyS0" not just "ttyS0"? I'm also assuming that ttyS0 is in fact your serial port and not something like "/dev/ttyUSB0"? (I'm thinking you have this right from your testing with minicom)
If it is /dev/ttyUSB0, it is possible for that device name to change inexplicably. I have seen /dev/ttyUSB0 suddenly turn into /dev/ttyUSB1, at which point Rivendell can no longer talk to the switcher.
There is something about USB devices that makes them prone to name changes. I've had to make a file /etc/udev/rules.d/10-ftdi.rules with the line:
BUS="usb", SYSFS{idProduct}=="6001", SYSFS{idVendor}=="0403", SYSFS{serial}=="A20e13EC", NAME="comusb"
...which will always make the USB serial port show up as /dev/comusb. However, the syntax is different on newer flavors of Linux (the above line works on Debian 6), and some USB serial adaptors don't have serial numbers, making it a challenge to disnguish them if you are using more than one.
