Very true: the modem (any modem; not just GSM) neither knows nor cares where its AT commands come from - it makes no difference to the modem whether it's connected to some PC software, a terminal with a human operator, some microcontroller or anything else...!
Similarly, the microcontroller's UART neither knows nor cares what may be connected; as far as the UART is concerned, it is simply a matter of sending bytes and receiving bytes - it is of no relevance whatsoever to the UART where those bytes go to, or where they came from, or what (if any) meaning they may have...!
