this doesn't disable the serial port, so you can still use them in your app.
what board/BIOS are you using?

  Ah.. But unfortunately I’m using both the serial ports that I have for other purposes in my app. But in any case enabling tty/consoles should happen later on in the boot sequence right? 

  My boot sequence looks like this:

  Device turned on –> Bios splash –> blank screen & blinking cursor –> plymouth splash –> app

  I’m trying to remove the blinking cursor before the kernel even starts booting.

  this line enables the console on ttyS0:
  T0:23:respawn:/sbin/getty –L  ttyS0

  so, if you comment out similar lines you shouldn't have any console any more.

    No, I haven’t enabled those entries. The only changes I’ve made to inittab is to change the default run level and launch my app.

    Hi,

    have you tried to make changes in "/etc/inittab": 
    comment "T0:23:respawn:/sbin/getty –L  ttyS0" and similar entries?

      Hello,

      I’m creating a kiosk type appliance based on Voyage 0.7.0 that boots into a custom X11 app. I want to hide all console like activity from the moment the device is turned on. 

      So far I’ve managed to hide everything by flashing a custom bios, tweaking init.d scripts, recompiling grub to disable the printfs.. etc, except .. for a blinking cursor that is visible for few seconds before the plymouth splash comes up. I’m guessing the cursor blinks while the kernel is being decompressed or while grub loads the kernel. Is there any way to hide that? 

      Thanks !

      Kapil
