I have a task where I need to send SMS with system problems alert through PLC. I think PLC is not matter. Let's say it have RS2323 and 485 on board. modem is something like this.

I have already енув to get nahd on documentation but all they have is technical specification.
how could I send AT commands to modem like this if I do not have manual for that? Is that sort of standard communication? What keywords to use for googling?
