connection will interface with your existing connection. Once the
connection is initiated it will take over as the “default route” for the
majority of your LAN traffic, specifically internet access. It’s
recommended to disconnect your LAN connection before using the
PPP (Dial-up) connection.

a display of RING on the HyperTerminal.

• The received signal is routed to head phone and is answered with
proper audio gain setting, which is programmable.

• The side tone signal can be minimized by setting level of MIC
feedback to speaker .

How to use it?
