New serial drivers use hardware signals to wake up.
In theory, the getty should be blocked as well, but some of them were compiled
with NOBLOCK, and so will open. Then the login process tries to run, and
freezes.
The solution: make pin 8 high. This will make the serial port believe a modem
has connected.
Possible alternate method: run the getty on /dev/cua# where the device
cua# had major 5, and minor the same as ttyS#
Hope this helps.
