If the "DE-9 RS-232" you presented means a true "RS-232C port", the signal voltage is +-12V.
If connected carelessly, it may be electrically damaged.
Unless you have a specific reason, I think using a generic "USB-UART" device is the smartest way to go.
If so, it is easy to obtain, and you can buy it for about $2 at Amazon etc. in most countries.
The important point is to make sure that it supports 1.5MBPS.
