Howdy, Just got my third SA Tivo (the Pioneer 810HS) and am using all of them in conjunction with Charter Cable's digital service. The STBs are all DCT-2224 models and, of course, the serial port on each is (as far as I can tell) disabled. They are all running 7.72 firmware, so they should be controllable if the ports were turned on. Right so far? I've had a number of lengthy chats with CSRs in regional support and at the head-end office for the system I'm on. The challenge has been in explaining what the serial port is / is used for. Once I get past that, the show stopper is that Charter's "system" (as viewable by a CSR) in this area doesn't have a place to check "turn serial port on". Tomorrow, I will be speaking with the person who "manages STB configuration" for my area. When I have this conversation, it would be very helpful for me to be able to explain what I am after in terms that he/she is familiar with. Specifically, when looking at Motorola "head-end" equipment, what is the serial port called? Is there a "feature code" to turn this on? What "screen" or "menu" is this likely to be found under on the Cable company's configuration equipment. In other words, I would like to tell the person "go to screen XX and look at item YY, that's what I'm talking about". Second, can anyone think of what the "downside" might be for the Cable company to turn this on? I want to be prepared to say "there is no downside for turning this on", but when I do, what arguments might they have that I could try to address? I hope that the more specific I can be in explaining this in their terms, the better chance I will have of getting some action. It is still possible (likely) that nothing will come of this, but I want to make the best case possible when I try. Any help would be appreciated. Thanks!
