The "NMEA listener properties" data source does not list any ports in its pull-down menu.
I would like to fix that, but even if ports were listed, I need to read from a file instead of a local RS232 port. I set up a named pipe to redirect the serial port from a remote computer to the Mango computer by using mkfifo. I can 'cat' the local file to stdout and view the NMEA stream updating in real time, so I should be able to read that FIFO file rather than /dev/ttyS0. How can I do that? Reading from a file is also a useful way to import old NMEA data into Mango.
But first, why don't I see any serial ports listed in the NMEA listener data source page?
