[bug #32115] No input in serial console

[darkbasic]

Follow-up Comment #4, bug #32115 (project grub):

First of all thank you!
I did a loopback test (CC pin 2 and 3) and it didn't work, so I searched in
my motherboard's manual and I found the pin legend:

I checked with the tester and they were connected in the wrong way:

I made a custom header-to-db9 connector and I mapped the pins following the
legend such a way: http://img831.imageshack.us/img831/5470/rightd.jpg

I double checked the mapping with the tester and I did the loopback test once
more: now it works! I also connected it to my cisco switch serial port: I can
see the switch output and I can control it with my keyboard!

So I rebooted once again to see if I can finally remote control grub: I can't
even see grub's output now :(
Both grub and linux don't work :(
This is very strange because loopback test does work now and I can even
control another device using my custom serial port...

Can you help me?
