While legacy PCs (post IBM PC/AT) typically use 9-pin RS-232 plugs, external modems are usually equipped with 25-pin RS-232 sockets. You can depend on Monoprice to have the cables you will need for this type of connection!
The connector heads are molded onto the cable and each includes a pair of thumbscrews to secure the connector to the PC or modem.
