INSYS WLAN serial 2.1 Overview AT Commands
Command Description
ATS0=<n>
Number of ringing tones until automatically going off-hook.
ATS0=<n
>
determines the number of ringing tones (received packets),
after which it automatically goes off-hook.
ATS0=200
Manual call acceptance
ATS0=0
deactivates automatically going off-hook when the local
port is accessed.
ATS0=1
Goes off-hook when the local port is accessed for the first
time (default)
For UDP/IP connections, ringing tones represent single (also empty) UDP/IP
network packets. For TCP/IP connections, connection requests of a remote
terminal („SYN“) are recognized as ringing tones.
While the UDP connection is established, the modules send an empty UDP data
packet in the beginning, so the remote terminal device accepts the connection
if it is configured with
ATS0
=1.
Important difference to modems: In TCP/IP mode, for
ATS0=0
the connection
acceptance is completely blocked, i.e. „
RING
“ is not displayed for a connection
request.
ATS1?
Number of received packets for connection request
Query of the number of TCP-SYN packets. This registry is used to achieve a
behavior such as, for example,
ATS0=2
.
ATS2=<n>
