Depends on the receiver. Some yes, some no. A data port is a necessary
condition, but not a sufficient one. >My receiver (an RCA, I forget model) does indeed have a "low speed data

I doubt it. Unless, that is, you already know know the serial port settings
(baud rate, stop bits, parity ... the usual stuff) and the actual codes
that need to be transmitted.
In any case, you'll need to find out the model number. Also tell us what
the port looks like (standard 9-pin serial? RJ-45 (like an Ethernet port)?
RJ-11 (like a phone line)? something else?)
One long shot -- a crude Web search turned up a Snapstream package for
controlling RCA DirecTv satellite receivers, specifically "RCA Model #4XXXX". It includes the right kind of cable to attach to an RJ-11 port on
the RCA end. You might see f that is what you need. Reference is http://shop.store.yahoo.com/snapstreammedia/rcadirbun.html

If they don't help ...
If it is a 9-pin port, the only real question is whether it is wired DTE or
DCE. I've never seen this answered for ANY cable box, so I suppose you'll
have to find out by testing. Just search Google for serial-port pinouts to
find the 2 relevant wiring diagrams.
If it is an RJ-45 ... I know of no standard pin assignment for them. If you
can't locate documentation for the box, experimenting to get the pinouts
will be a challenge.
If it's something else ... who knows? (Except for old DB-25s, and I doubt
it is that.) >I did try searching the mailing list archives, but I couldn't really find
Provide all the detail you can. Including if there is any information about
using teh box with a TiVo or any other commercial product ... what does
your cable company *say* the port is for?
Figuring this stuff out is a bit like a scavanger hunt. Finding actual docs
for the box is improbable, so you need to piece the relevant details
together. You won't find a cookbook for this anywhere.
