Bash, serial I/O and Arduino

Question

So, I\'m in a bit over my head, and I feel like I\'m very close to a solution, but it\'s just not working quite yet. Here\'s my situation:

I\'m working with an Ardui

Answer 1

I struggled with this problem also, trying no end of stty settings and tricks to cat my files to /dev/tty.usbserial-FTF7YNJ5 (in my case) whilst standing on one toe, etc.

Then I did an ls /dev and noticed /dev/cu.usbserial-FTF7YNJ5 -- oh, what's this? Apparently, a 'calling unit' version of the device that doesn't expect or provide any flow control. Dumps bytes to the port. Exactly what I needed.

So just do: cat super_file.bin > /dev/cu.usbserial-XXXXX

Hope this helps. And only now that I know the answer, I found this: http://stuffthingsandjunk.blogspot.com/2009/03/devcu-vs-devtty-osx-serial-ports.html
