Cannot Access AT-Commands

I have switched from a the originlly delivered WP8548 to a WP7607 on my MangOH red, the problem is now i cannot access the AT!commands like i used to via the CF3 port. I also tried reinstalling the drivers, with no success.

Thanks in Advance!

Do you have the uart console port?
You can also enter AT command there.

Nevermind i found it. Somehow my PC doesm’t seem to label it. I can access it vie TeraTerm on COM13, it just isn’t labeled as AT Port like before. Is this a driver Issue?

it should label as modem port.
