I'm using util-linux-2.20.

/etc/inittab has the line below:
s0:2345:respawn:/sbin/agetty ttyS0 9600 --long-hostname --noclear

When I  login  on a serial term,  I type username, but nothing appear
on the screen, just as input password.

Only when input a wrong password, and try again, I can see the
username as I typed,
but that was done by /bin/login

It looks like the "ECHO bit in termios.c_cflag" was not properly set
before the get_logname() been called.
