How to Send AT Commands to mgetty?

Hello All,

I've been working on something which requires a dialup USB Modem. I have been using minicom with success entering "AT Commands" directly into
the terminal window that shows after running the minicom command. I had already configured the modem through minicom and was able to successfully
call into the USB Modem and hear the dialup connection tone.

But I am now trying to use mgetty to do the same, but I cannot figure out where to enter the AT Commands. I found a few different sites that talk about
using mgetty along with AT Commands but I cannot figure out WHERE these commands are entered. In minicom, I simply run the minicom command, then
when the terminal window refreshes and it shows the minicom terminal I can simply type the command directly into the window there and hit enter and it takes the
command. But mgetty, if I try the same thing nothing happens after entering the command so I'm assuming there is another way...?

I know mgetty is supposed to be started through init tab, so are you supposed to create a "script" like file for passing commands to the modem with mgetty?
I also read something about "init-chat", and how that is used to send command sequences to the modem, but don't know where to use them...?

If anyone has any ideas or suggestions on how to do this, or if anyone can point my in the direction of a tutorial for how to do this, that would be
greatly appreciated.

EDIT: As I'm writing this I was re-reading the manual page for mgetty and came across "mgettydefs", is this what I am looking for...?

Thanks in Advance,
Matt
