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?

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.

I am holding in my hand a Jam Studio KG-TAB1 drawing tablet, (c) 2000, that interfaces through a connector consisting of three rows of five holes, very much like a VGA connector but which surely cannot be VGA, given the application as an input device. Other people discussing "the same" device mention its "USB" and "PS/2" connectors, which suggests serial communication over several stages of hardware evolution, further supporting the theory that this IS a serial device/port. I have also found online documentation of what claims to be the pinouts for serial communication on this style of connector.

The plug, in question, is 15pin and your answer does not apply. I am resisting the urge to downvote it, as I am supposed to. – Rohit Gupta Feb 01 '23 at 01:04

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