This is a female Type 'D' 9-pin subminiature (DB-9F) connector that interfaces
the M&C functions to a remote location; the remote location can be an M&C
computer located away from the modem, but attached via cable to the remote
connector. This DCE interface is user selectable for either EIA-232 or EIA-485:
