15 Pin Serial Cable?

Question

Stumbled across what appears to be a 15pin serial cable when cleaning out the equipment room today. I'm familiar with 25 pin and Any idea what these are commonly used for?

Answer 1

Hard to tell without a pic, but I'd guess its a 'DB Connector' or 'Game Port' connector.

DB-15 (DA-15 and DE-15)
Two DB-15 connectors are widely used. The larger, two-row female DA-15 is the game port on a PC, and the smaller, three-row, female high-density DE-15 is the VGA port.

The Game Port was used for joysticks, midi devices and other peripherals.

Answer 2

A couple of our earlier generation terminal concentrator units ran on an RS-422 loop that used DB-15 connectors and cabling.
