You use the cable that came with for a connection to a terminal or serial
port on your pc. You need a slightly different cable for the connection
to the modem. Here's the pinout for the S0 to modem cable.

RJ45 DB25

1 rts 4
2 dtr 20
3 txd 2
4 gnd No Connection
5 gnd 7

BTW this pinout is available in the Hardware Installation Guide pp. C-2
