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

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-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)

If the SSL/TLS Security features are not enabled in the software or there has not been any SSL/TLS session
