Update device-specific.markdown (#9099)

Browse Source 
* Update device-specific.markdown

Expand Aeotec Z-Stick section to provide alternative "pipe to cu" syntax for enabling/disabling "disco lights" on systems where redirection to serial devices doesn't work because the baud rate on the serial device reverts to 9600 when haas isn't running.

If the above two commands give errors about not having that device, you should try replacing the `/dev/serial/by-id/usb-0658_0200-if00` with `/dev/ttyACM0` or `/dev/ttyACM1` (depending on which tty your aeotec stick is addressed to).

On some systems, such as macOS, you need to pipe the output of the `echo` command, rather than redirecting to the serial device, to something like `cu` (replacing `/dev/zstick` acccordingly) to properly set the baud rate to 115200 bps:
```bash
echo -e -n "...turn on/off string from examples above..." | cu -l /dev/zstick -s 115200
```
