For a few months I have been saying I have a US Robotics 5660A modem and\nthat the caller ID on it works. I was going to answer another post today\nwhen I decided to check the US Robotics site for the price. I have also said\nthat the cheapest model does not work. Well 5660A is the cheapest model\n(.95). I opened up my computer case to confirm and what I have is a 5699B\n(.95). I am very sorry for those that this caused headaches. I tried them\nboth and I got the model numbers jumbled up in my head.\n\nUS Robotics 5699B (.95) works. 5660A (.95) does !!! not !!! work.\n\nI am truly embarrassed. I felt a sweat coming on as I realized what I had\ndone. I hope I haven't caused too much trouble.
