I've got an old (compiled, no source code) application that requires a GPS connection on a serial port. Of course, none of our field laptops have anything like that - it's all USB these days. What I need is some kind of a "bridge" daemon that will read the NMEA-0183 sentences from the USB port and write them to the serial port.

Write them to the serial port? There isn't any, if your laptop doesn't have a serial port. Your GPS mouse is USB, isn't it? So it should show up as /dev/ttyUSB0 or such and be handled by the usbserial kernel module. All you need to do is to soft-link the USB device file to the one your legacy application expects, e.g. ln -s /dev/ttyUSB0 /dev/ttyS0
