Voice Commands

The MultiModemDSVD uses DSVD technology to achieve simultaneous voice and
data operation over a telephone line. Establishing a DSVD connection is like estab-
lishing a regular data modem connection. Initiate the call to another DSVD modem
using normal dialing (ATD) and answering (ATA) procedures. The modem can
switch from a regular phone conversation into DSVD mode and back to phone con-
versation. A connected telephone can be used for voice communication during
DSVD mode.
In addition to the following commands, the MultiModemDSVD supports voice com-
mands that are mainly of interest to developers. Information about those commands
can be found in the Voice #V Commands Developer's Kit, available on the Multi-Tech
Web site at http://www.multitech.com/support/manuals/82039201.pdf.
