Ideally I would like a cable that is USB at the PC end and serial RS232 at the receiver end. It need not have the null modem crossed pins because the exising null modem can simply be connected in series between the sat box and the new cable.
I know these adapters exist but I need one with a good long length on it (oo er missus).
Any pointers as to where to go?

I think that you should be very careful about using the wrong connections, as you might damage your sat box.
If you don't have an RS-232 interface in your PC, then I would consider buying a serial interface PCI board to create the RS-232 outlet. Check compatibility with your MB and O/S. It shouldn't cost that much.
Hope that you have a free extension slot in your PC.
I hope that I am wrong and someone else would say no problem just use USB/DB-9 adapter (which I have from an old Logitek mouse), but I wouldn't use it without looking at the whole technical aspects first.
