First off, I know the video I am linking is very bad. It was posted a while ago, and Youtube has diminished the quality, along with I just wasn't all that good at filming, nor knowledgeable at the time. I consider myself a little more versed in hardware since I acquired this two years ago, but I'm still stumped. I don't have a camera with which I can re-record a video, and it's been bothering my lately that I could rebuild my compaq portable, but still don't know what this does.
To add a little info to the video:
All other cards are the same, they run off an AC current. Each has an individual power switch, a female db25 connection. It has two phone connections with all four lines connected, so it's not JUST for data use, I presume. It can power the lines too (or feed off a power connection?) The LEDs are labled TM AA HS OH SD RD TR CD.
Thanks for your time
