I don't know if it's going to help you with this issue, but if you can hardcode a path to the serial port somewhere, take a look in the "/dev/serial/by-id" directory - it has symlinks to /dev/tty* entries that correspond to hardware serial ports currently connected. Names of the symlinks are generated from some kind of hardware IDs, so should be the same, no matter the order of enumeration (unless your hardware doesn't expose an unique ID that udev, or whatever makes those symlinks, could use)
