First, make sure that the SMS cat is connected to the host normally and install the SIM card.
Use a Super Terminal to test whether the SMS cat can be used.
Install minicom:
# Sudo apt-get install minicom
After the installation is complete, run
# Sudo minicom-s

Compile or not. Check the log. Okay, it's a permission issue. Then run it in the Super Terminal:
# Sudo chmod 777/dev/ttyS0
Re-compile, the phone received a text message, OK.
In Windows, replace the port number with "COM1.
