There was a post awhile back about how to tell if you need to get a new ROM for your Mark XII. Mine failed the test, so I called Anchor. They said that the ATI1 command reports a checksum, and that if you get 254, 083, or 104, then you should call them. I got 129, and they said that is fine. Also, if AT? responds with an "Error", this means that you have a ROM that is capable of sending a Break. If not, the upgrade is $40. At leat, this is what I think he said. -------
