The 3451 can be set up to tell you what speed it answered at via one of the RS232 control lines, but you don't need to use this. The usual trick of having getty cycle between 1200 and 300 if it gets something it doesn't understand is sufficient, and presumably what you have to do with any of the other modems anyway. Thus the 3451 has an asset of dubious usefulness, but it certainly isn't a liability. The Anderson-Jacobson 1259 is virtually a clone of the garden-variety 3451; it doesn't have dialing capability of any sort yet but AJ claims they're working on it. The 1259 has circuit boards which are virtually identical to the 3451 except that the Vadic has more expensive components in some places (gold-plated IC sockets for example), and is functionally identical except that you can't tell it not to answer the phone without dropping DTR (which doesn't matter for computer-controlled use). It certainly handles 3400 protocol as well as 212 and 103/113, and is somewhat cheaper than the equivalent Vadic. I'm typing this in via a 1259.
