I need a full-handshaking null modem cable. Any ideas ?

I lost the cable for my LPKF PCB mill.
I know I could build one, but I really want a molded cable.
It needs to be full-handshaking null modem. I tried two already and they didn't work because they were not full handshaking.
It needs a DB9F on one end and a DB25F on the other.
I'd like about 12 to 15 foot long, but I'll take anything right now.
Any ideas where I could buy one ?

Use BASIC on the Propeller with the speed of assembly language.

It's only 10 feet, though. You might be able to get a longer, more standard cable and put an adapter on one end.

I have used them though not for serial cables.

PS I'll be passing through PA, maybe I can drop it off.
Are you aware of what a full crossover requires? Of course there are variations, but this is the true (mainframe computer) crossover. I am presuming async...
GND

TXD

For sync you need to add clocking
TXC

Sometimes external clocking is provided on (pin 24???) which is wired to all TXC & RXC.
