Hi
We recently got a new module: WP7608 to be used on Mangoh Red. It is running on latest firmware. Currently the AT port is not getting shown in Windows. I am getting only two ports: DM and NMEA.
Earlier, we were using WP7502 where COM6 used to appear as AT port for modem commands.
As Matt says, the modem interface should be there, and AT commands are supported on that interface (same as WP7502). On WPx5 series, a second AT Port interface was provided, which was removed (or more accurately, not added) on WP76xx and WP77xx. There is some ongoing discussion about re-introducing that interface, but please feel free to describe your need for that interface here, or by private message if you prefer. A collection of use cases helps adjust priorities or might let us recommend an alternative. Hopefully the Modem interface gives you everything you need
