RING“ or the code “2“.
 
This command must be the last command in an AT command line. 
ATA[//<UUS1data>]
 
<UUS1data>
  data transmitted with UUS1 signaling 
ATB 
B channel protocol 
Transmission protocol for data communication in the B channel. 
ATB0
 
V.110 asynchronous (i.e. for BBS access) 
ATB1
 V.110 
synchronous 
ATB3
 
HDLC async to sync conversion (PPP asynchronous, single link 
PPP) (e.g. for Internet / dial-up network access) for internet / RAS 
network access)
 
ATB4
 
HDLC transparent (octets are packed into HDLC frames)
 
ATB5

AT%B 
Set local baud rate 
Sets the local baud rate of the INSYS ISDN TA to the desired value (fix value) or to 
auto detection. When auto detection is set, the INSYS ISDN-TA will recognize the 
required baud rate with every newly entered AT command by the terminal soft-
ware (PC). With all other settings the PC must use the same baud rate.
 
Must be the last command in an AT command line.

will be sent with the baud rate 115.200 bit/s.
