A little background: a PC serial COM port is RS232 protocol. Among other things it specifies signal voltage of +10V to -10V (approx).
The L297 and most other motor driver chips are not designed to directly interface with serial data. In most cases a micro-controller is needed to receive the serial data and then set the appropriate motor control lines
Now, most RS232 also have a number of 'control' lines such as CTS, RST, DTR, etc
