Call Control Commands
This section describes the Call Control commands.
Command Description
AT%A2=n Protocol Control: Specifies the protocol you want to
use for your ISDN connection.
n=2
V.120 rate adaption protocol.
n=95
PPP asynchronous to synchronous conversion.
n=96
Multilink PPP connection (default).
Note:


Both PPP and Multilink PPP require that a PPP
communications stack be installed on your computer.


Both the local terminal adapter (DIVA T/A) and the
remote device must be set to the same protocol.


If your workstation is configured as a Windows for
Workgroups RAS client, you must configure the V.120 rate
adaption protocol on the DIVA T/A workstation and the
remote device (RAS Server ISDN adapter).


Multilink PPP does not support the callback feature
used by some servers for security purposes.


When using Multilink PPP for incoming calls, only
SPAP or PAP authentication are supported.
(Windows NT only) In order to support incoming calls
with Windows NT RAS Server, you must enable the
parameter “Allow clear text authentication” in the
RAS Server setup. Refer to the RAS online help on how
to configure this parameter.
Note: These parameters are static. They do not take effect
until you restart your DIVA T/A.
AT%A95=c Incoming Data Call Answer: Sets how incoming data
calls are handled (accepted or rejected).
c=E
All incoming data calls can be accepted either by the
DIVA T/A (ATS0=1) or by the application (default).
c=D
All incoming data calls are rejected upon receipt
