The manual for agetty states that it prompts for user name
but what I really see is as above.
I can run as user or root makes no difference.
Can supply root as name or root password.
I will explain my set up.
I have a computer which I am logged into.
I can be root or user.
A serial port is connected by cable from the computer
to a microcontroller.
Using for example the cu command.
cu -l /dev/ttyS0 -s 9600 --nostop --parity=none dir
And I establish two way communication computer-microcontroller.
Similar situation with minicom after setup by root with minicom -s.
Can also with more difficulty use miniterm.
Now try agetty
agetty 9600 /dev/ttyS0
Never get passed this point.
Have tried all combinations and various switches.
What password is agetty looking for?
