Serial printf not showing output on ubuntu
I am using ubuntu 13.10, terminal and gnu screen. Member of the dialout group with modemmanager removed.
No output appears on screen, yet when I press a key on the pc keyboard the usb com light flashes on the mbed.
Serial pc(USBTX, USBRX);
pc.printf("Hello World!\n");
My arduino can send prints to the serial monitor no problem.
Any help on what further to try would be greatly appreciated.

If I try running
screen /dev/ttyACM1 9600 8N1
I get the following.
Cannot open line '/dev/ttyACM1' for R/W: Device or resource busy
Sorry, could not find a PTY.
I am using a LPC812-MAX.
Have you checked this thread? http://mbed.org/forum/mbed/topic/3977/
