Creating a virtual serial port

command linegoogle mapsterminal

I'm trying to create a pair of virtual serial ports on my mac. This is fairly easy to do with many shareware programs on a PC. I figured there would be some uber-powerful shell command to do this in one line, but I can't find it.

I want to send NMEA data into one port, and have Google earth read the data out of the other.

Any tips?

EDIT

MrDaniel's /dev/ptypx comment seemed to be interesting – I can pull it out of /dev/ttypx just fine in terminal.
But Google earth seems to be reading cu.deviceName instead of the /ttypx deveices..

specifically (Old Pro):

When trying to import the current location using a GPS (or NMEA stream piped through our virtual serial port), we go: Tools > GPS > Realtime to get to the import screen.
After selecting the NMEA option, and enabling realtime tracking, it looks for connected devices, and seems to look at:

  • usb:
  • /dev/cu.Bluetooth-PDA-Sync
  • /dev/cu.Bluetooth-Modem
  • /dev/cu.iPhone-WirelessAP

Even with our ttypx serial port operating ok, it doesn't look for it.
I would like to get the data from that device into Google Earth.

Google has an extremely useful tool for Arduino developers and it simulates serial ports very well on OS X for testing purposes. It only works until 10.6
