Commands and the active port
In most cases, when entering AT or text commands, the command only affects the settings for the
active port. This is usually the port to which you are physically connected, but you may, if necessary,
set the active port to another port of your choice using the AT\PORT=N command, where N is a port
number from 0-3.
