I am attempting to send data to my arduino via usb from python and/or java. On my ubuntu machine I had no trouble opening the port as a file and writing to it. Now on my Mac machine I am trying the same thing but when I try to open the port in python with
file = open('tty.usbserial-A600egTb','w')
python just sits there and fails to execute the command as though it were waiting for something. A similar thing happens if I try to route output from java programs to the port from command line.
I had to modify the permissions in Ubuntu, however I have tried this in OSX to no avail. Could it have something to do with the transfer speed rate? If so, how do I alter the baud rate coming from my computer?
