Questions about TRS-80 Expansion Interface

I need to know where the serial port connector is on a TRS-80 Expansion
Interface. I have two of them. One has its ports labeled, and one of the
ports is labeled "MODEM" but it is simply an edge connector. Is this the
serial port? If so, what's the pinout?

Any help would be greatly appreciated. Thanks!
