Enabling user logins with a getty service

z/VM guest

Instantiate getty services for terminals to allow user logins.

Procedure

Perform these steps to use a getty service for enabling user logins on any dynamically added real or virtual 3270 terminals:

Enable the new getty service by issuing a command of this form:
```
# systemctl enable serial-getty@<terminal>.service
```
where <terminal> specifies one of the 3270-tty<N> terminals and <N> is an integer greater than 1.
Note: You specify terminal 3270/tty<N> as 3270-tty<N>.
Optional: Start the new getty service by issuing a command of this form:
```
# systemctl start serial-getty@<terminal>.service
```

At the next system start, systemd automatically starts the getty service for you.

For 3270/tty2, issue:

# systemctl enable serial-getty@3270-tty2.service
# systemctl start serial-getty@3270-tty2.service
