AT&R<n>
Polarity of the CTS control line
For controlling a RS485 driver (see also AT&K8). The CTS signal is set to active
or inactive when the device receives on the serial interface:
AT&R0 CTS signal inactive (low) for sending
AT&R1 CTS signal active (high) for sending (default)
AT#RBT
AT#RESET
Restart
The device is rebooted. All parameters are reloaded from the permanent
memory.
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
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 devices send an empty UDP
data packet in the beginning, so the remote terminal device accepts the con-
nection 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 connec-
tion request.
ATS1?
Number of received packets for connection request
Query of the number of TCP-SYN packets that were received up to now. This
registry is used to achieve a behavior such as, for example, ATS0=2.
This registry is a pure read register (Read-Only).
ATS2=<n>
Character for escape sequence
The escape sequence consist of a series of a 1 second pause, 3 times the es-
cape character and 1 second pause again. (The pre and post run time of 1
second can be changed using ATS12)
ATS2=0...127 Determination of the escape character as ASCII code
ATS2=128 Functionality deactivated
ATS2=43 (default)
ATS3=<n>
Carriage Return – CR
ATS3=0...127 Determination of the character as ASCII code
ATS3=13 (default)
The setting is not stored with AT&W in the permanent memory.
