Using a Samsung remote to control a CISCO 4642HDC cable box--is this possible?

I'd like to use my Samsung TV remote control to control my Cox-provided CISCO cable box. BUt I can't locate the standard 3-digit universal remote code for CISCO, if there is one.  In the Cox-provided universal remote instructions, it says to use a special procedure (SWAP-A buttons) to program the CISCO box. Does this mean it's impossible to control the box with my Samsung remote?

(I have called support lines at Cox and Samsung so far, and the CISCO site just points back to "your cable provider" (i.e., Cox) for support, so . . . No one seemed familliar with the issue.)

Thanks,

Martin Smith
