Oh and how long would you want the cables?? Couple of metres??? Standard you buy is usually 1M or 3M... I've had a look around the net and cant find a splitter one like you said. I thought they did them!?!!?
EDIT!!
Oh fine Il make one with a male one end splitting out to two females from the back of the male.
Il post up some pics tomorrow either at work or here so you can confirm if I've followed what you want correctly!

If thats RS232 then yeah
LOL Il knock it up, post up some pics and we'l go from there! Saves you spending s**t loads on something that don't work
Il bump this tomorrow lunch time I reckon 
Is that the pin out your after?? Standard? Obviously ignoring the D25 bit!
Just realised thats a null loopback pinout but you get what im asking you!?!
By the sounds of what he is wanting to do he wants null modem
style cable anyway.
Code:
/---> Slave 1 RX (Pin 2)
Host TX (Pin 3) -|
\---> Slave 2 RX (Pin 2)
/---> Slave 1 GND (Pin 5)
Host GND (Pin 5) -|
\---> Slave 2 GND (Pin 5)None of the other pins can be connected (it will stop the cable from working) as RS232 is not open collector/drain.
Ok I've nicked a Normal Lead off our telecoms eningeer.
Sorry m8 in fact I need a Male D25 to two female D9 ( I was thinking of the Samsung Systems doh!)
D25:
Red -> pin 2
Blue -> pin 3
Green -> pin 4
Yellow -> pin 5
White -> pin 6
Black -> pin 7
Brown -> pin 20
D9:
Red -> pin 2
Blue -> pin 3
White -> pin 4
Black -> pin 5
Brown -> pin 6
Yellow -> pin 7
Green ->pin 8
If you can't do this m8 - then no worries.
also if you can make it 3m that would be super!

well yes - but that lead they use is to programme the system also.
Cool. As TX is shorted on both 9 ways, if you need to transmit (i.e to program) you'd need to unplug one of them as both PC's will be driving the TX signal.
Alternatively you could not wire TX on the 9 ways but this would prevent you from using this cable as a programming cable.
If the phone system uses hardware flow control this cable won't work either as pins 4 & 7 on the 9 ways would be shorted together.
Depends on the phone software and the software you're using to capture the data.
