We have 3 S2s (all single tuner) attached via serial ports to our Motorola cable boxes (2 are DCT2244, one is DCT2524). About 2 days ago, all 3 lost the ability to change channels. The cable remote still changes channels successfully. All connections have been checked, and Guided Setup and Settings run and re-run, checked and double checked.
We talked to Comcast, and they are playing dumb (and unhelpful). It sure does feel as if they've pushed some sort of change they won't admit to.
I remember having to use IR connectors back in the bad old days, and I sincerely DO NOT want to go back there. Nor do I want to "solve" this by having to buy new machines, when these have been plugging along just fine for our needs until now (one is lifetime).
Is there something we're forgetting? Any ideas about what else to check? Any experiences with Comcast disabling serial control in these boxes?
