Steps

1. First copy the template:

# cp /lib/systemd/system/serial-getty@.service /etc/systemd/system/serial-getty@ttymxc3.service

2. Then edit the file and modify the agetty line:

[Service]

Type=idle

3. Create a symlink:

# ln -s /etc/systemd/system/serial-getty@ttymxc3.service /etc/systemd/system/getty.target.wants/

4. Reload the daemon and start the service:

# systemctl daemon-reload
# systemctl start serial-getty@ttymxc3.service
# systemctl enable serial-getty@ttymxc3.service

5.vim /etc/init.d/rc.local 或者

vim /etc/init.d/startala.sh

#start serial-getty@ttymxc3.service
systemctl daemon-reload
