GETTY

[Kenneth Galle]

That's how I understand it to be.
If I telnet in and check the jobs running (ps -axf), I see:

608 tty1     SW     0:00 [login]
872 tty1     S      0:01  \_ -bash
for a logged into console session (Alt-F1),

609 tty2     SW     0:00 [mingetty]
for a  not-logged into console session (Alt-F2),

8509 ?        S      0:00  \_ in.telnetd
8510 pts/0    S      0:00      \_ login -- ikenneg
8511 pts/0    S      0:00          \_ -bash
8523 pts/0    R      0:00              \_ ps -axf
and this for the telnet session.

mgetty is used when serial ports (and possibly modems) are involved, and
mingetty on the "tty" console terminals.
