SENA Serial_IPTM Redirector 4.3 - Manual (Page 61)

following command:
AT+SCS=56,128,RC4,DES
Entries may be omitted from the list, in which case the defaults from the GUI are used. For example, to set 40-
56 bit ciphers using the current families specified in the GUI, the application sends the following command:
AT+SCS=40,56
To use the current cipher strengths from the GUI, but only use RC4, the application sends the following
command:
AT+SCS=,,RC4
The application may query the current settings using the command below, which shows the output when the key
lengths are restricted to 40-56 for RC2 and RC4:
AT+SCS?
40,56,RC2,RC4
OK
The application may query the final cipher set using the command below, which shows the output when the key
length are restricted to 40-56 for RC2 and RC4:
AT+SCS=?
EXP1024-RC2-CBC-MD5
EXP1024-DHE-DSS-RC4-SHA
EXP1024-RC4-SHA
EXP1024-RC4-MD5
EXP-RC2-CBC-MD5
EXP-RC2-CBC-MD5
EXP-RC4-MD5
EXP-ADH-RC4-MD5
EXP-RC4-MD5
OK
Negotiated Cipher Set (AT+SNS)
This command may be used in only one mode: to query the cipher and strength negotiated on the last SSL/TLS
session. For example, for a session that negotiated 128-bit RC4:
AT+SNS?
RC4-MD5(128)
OK
If the SSL/TLS Security features are not enabled in the software or there has not been any SSL/TLS session
