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.
