S82=n

Enables UDP auto answer (half-open) mode.

n=0 : Normal mode

n=2 : Enable UDP auto answer mode.

S83=n

Set or query UDP auto answer idle time-out. If no data is sent or received before the time-out occurs, the current UDP session will be terminated. While a session is active, packets from other IP addresses will be discarded (unless *UALL is set).

n=1 - 255 Time-out in seconds. n=0 : No idle time-out (Default).

*DU=n

The dial command always uses UDP, even when using ATDT.

n=0 : Dial using the means specified (default).

n=1 : Dial UDP always, even when using ATDT.

Note: When this parameter is set you cannot establish a TCP PAD connection.

*UALL=n

Accepts UDP packets from any IP address when a UDP session is active. If there is no UDP session active, an incoming UDP packet will be treated according to the UDP auto answer and AIP settings.

n=0 : No effect (Default).

n=1 : Accept UDP data from all IP addresses when in a UDP session.
