It should say they will be compatible with the manufacturers who currently sell 75-80% of modems. However some of the existing non-USR modems do have flash upgrade capabilities. > It is also worth noting that long before V.32 > appeared on the scene, USR was transferring data at 9600 (and later > 14.4Kbps) with a proprietary protocol called HST, and it was quite popular > even though only USR HST modems supported it. At the time another company called Telebit had a 9600 bps protocol called PEP that was totally incompatible with HST. It was also quite popular. But that was back when anybody could by two identical modems and they would interoperate. However, with 56K you can't do that. If both ends of the connection are running a USR 56K modem it will not be possible to get any faster than 33.6kbps.
