Connect modem to PC and use some serial terminal software. Make connection to modem via appropriate COM port. Then type something like AT&F and hit Enter.
If you see answer "OK", then you are on the right way. Now you can start to experiment with AT commands.

Easy. Make some changes to settings, turn modem off, on and see if your changes are still there :-)

First simple thing: call your modem line from other regular or mobile phone to see if it picks up and when.
ATA - in most cases sets modem to autoanswer.
Then see S-registers.
ATS0=5 for example sets number of rings before answer to 5.
After off/on with ATS0? check if 5 is still there. If not, then try first to save settings like: AT&W0

Modems are different.  Sometimes it is ok just to give above mentioned commands and modem remembers them. Sometimes usage of modem profiles F0, F1 is ok. (AT&W0; AT&W1 to write them, AT&F0; AT&F1 recall them).
It is also possible to pass all settings to modem in one init string, like:
