It depends on what is on the other end of the cable........

A null modem cable would be if you are attaching it to another computer directly serial port to serial port.

I've never heard them referred to as straight through cables before. 
I thought they are referred to as simply a serial cable or modem cable, but I never pinned one out before either....

Then start with the straight thru cable

If that doesn't work try this

SSC -------------------------- Modem
---------------------------------------------
GND 1  ----------------- 1  GND  frame ground (this line is OPTIONAL)
TXD 2  ----------------> 2  TXD  transmit data (from SSC to modem)
RXD 3  <---------------- 3  RXD  receive data (from modem to SSC)
RTS 4  ----------------> 4  RTS  request to send (for hardware handshaking)
CTS 5  <---------------- 5  CTS  clear to send (for hardware handshaking)
DSR 6  <---------------- 8  DCD  data carrier detect (from modem)
GND 7  ----------------- 7  GND  signal ground (for all signals but pin 1)
DCD 8 (leave unconnected!)
DTR 20 ----------------> 20 DTR  data terminal ready (to hangup modem) 
Have the ends of this cable labelled "SSC" and "Modem", as it will not work correctly if plugged in backwards
