Last week I heard a report on a financial news program that Digital Communications had just announced a breakthrough 9600 baud modem. I haven't seen anything in print about it yet. From the way it was reported, it is presumably not the half duplex 9600 baud technology that has been around for a while. Does anyone know any details?

PC WEEK for July 16 has a front-page story on it. They apparently use multiple narrow channels, etc. to get the higher bandwidth. They also use what they call 'adaptive duplex' to simulate a full-duplex connection. They have internal CRC checking on transmitted data. They will be aiming initially at the PC market, it seems. They are bundling in a stripped-down version of the Crosstalk PC comm package (presumably w/o protocol transfer functions). Announced pricing was $1995. for PC built-in, $2395. for stand-alone.

There is an international standard for 9600 baud, full duplex, async, dialup modems. It's CCITT V.32. However, I don't know of any products that implement it yet.
