Hi,
As gerliczer said, the cable as shown in the hardware gallery is for a direct link to a PC parallel port. I presume that this piece has been homemade. To the best of my knowledge, there are no commercial offers for this kind of cables.
Since the Plus/4 does provide at the userport only TTL (5 V), you would require a level-converter to cope with the 12 V modem voltage.
The Plus/4 has an UART chip (6651 at position U3), enabling the Plussy to up to 19200 Baud.
So you'd need a cable and a level converter, besides of probably a Plus/4 PRG for communication with the modem.
