Is there an OS X terminal program that can access serial ports? Install the 'Virtual COM Port' driver and look for the. Another serial terminal for Mac OS X is. Creating a virtual serial port on OS X. I'm attempting to create a virtual serial port connection to enable. 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. 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. I think what you are looking for is a Pseudo Terminal as noted in, it looks like Mac OS X has built in in /dev and it seems like this can do what you want to do e.g. Two programs talking together via a 'virtual' serial port. Pseudo terminals are pairs of devices such as /dev/ptyp3 and /dev/ttyp3. There is no physical device directly associated with either of them, not even a serial port connector. But if a program treats ttyp3 like it was a serial port, what is read and written to that port appears on the other member of the pair ptyp3 which another program uses to read and write to. Thus two programs talk to each other via this method and one program on ttyp3 thinks it's talking to a serial port. It's something like a 'pipe' between these two tty's. Additonally, the program my by useful to you as well.
