New to modems, need custom rules

Hello everybody.
I’ve read Mikrotik is the place to be for fast reliable communication so here I am.

I am relatively new to modems so I am not exactly sure what is possible and what the price range would be.
I want to send a command and a text to a modem which prompts it to forward the text to predetermined numbers at a predetermined time interval until it receives a specific response.
I would like to be able to change the numbers, the response, and the time intervals through a com port (usb com)

I’ve already done this on a fairly simple modem using AT commands, but I want to export as much of the functionality as is possible over to the modem itself.
Is this possible and what would the price range be?

Modems are pretty dumb devices, do what you want to do is beyond modems’ intelligence.

You can script things in RouterOS, but IMO scripting is not very flexible and you can’t add nifty little tools which can help. Personally I’d go with a small general-purpose computer (e.g. raspberry PI) running linux, connect a modem and try to script things according to functional specifications.
