Does anyone know anything about these modems? They claim 9600 baud over regular phone lines. Anyone know how these things are over long distances? How about over alternate carriers, other than AT&T? -Mike Grant p.s. they go for $895

Ok, here's the scoop: I called them up. It uses V.29. It's software selectable for 4800, 7200, or 9600 baud. It's full duplex, except, not really. It has about a 1 second timeout before switching directions. It's $895 for the IMB-PC version, $995 for a standalone RS-232 version. She said that it works fine over AT&T, but not so well over alterrnate carriers. The ad apeared in Byte, Dec. 85, p. 74. The address is: Electronic Vaults, Inc. 12347-E Sunrise Vally Drive Reston, VA 22091 (703) 620-3900

Is what you're saying that the modem is really half-duplex but with a one second timeout to simulate full duplex. For fast typing that will not satifice. For a CRC run as a protocol on top they would do well for a data tranfer modem. I will call and get teh techy spec. Maybe get a trial modem and link to one of their own sites/ Let's see what happens. Any other replies ? Dave
