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