After ogin/assword characters typed are munched away until prompt?

Hi,

it's been bothering for ages just never wrote the email and I find it
lately when using serial consoles (bhyve nmdm or physical often over USB)
a lot.

In the old days you would enter username and password and keep typing
your first command and it would work.

These days everything I type after password<enter> before I get my
prompt (rough estimate) while motd is scrolling .. is lost.

I often find myself with half a command name "not found".

Where are those characters lost to (or thrown away) that are typed in?

Anyone any ideas?
