It's one of those "oops" moments when you dig that old serial cable out of your bottom drawer and crawl under your desk only to find your new PC doesn't entertain such archaic forms of connectivity any more (and indeed, nor should it!)
Yes, the excitement of setting up a fancy new telly was slightly dulled by the realisation that I couldn't program my ancient Philips Pronto remote to switch the wretched thing on!
Rather than buy a new USB-friendly remote I tried this gizmo, and it works beautifully.
Although it came in a rather gaudy translucent turquoise colour rather than the black shown it does have 1.5m of good quality shielded silver cable and an additional 9-way to 25-way converter (handy if for some reason you have a desperate desire to resurrect your old US Robotics 14400 modem...?)
The business end of the cable has the 9-way male serial socket (thus replicating the com port on the back of the old PC your mum is now using) and contains the necessary "rosetta stone" PCB and chip within its moulding. The drivers (98SE/2K/XP) for this are contained on a small-format 8cm CD, so if you have a slot loading optical drive I'd recommend checking it will handle this first, or use another machine to copy the drivers onto a memory stick.
Considering it worked brilliantly, cost only £7.30 all-in and arrived well within 24hrs, a 5 star rating is a no-brainer!
I'll just hide its gaudy turquoiseness back in the bottom drawer...
