CGAUTH on HL7900

I type AT+CGAUTH in hl7900 and it return

at+cgauth?

+CGAUTH: 1,0,

what 0 mean , i don’t see value 0 of CGAUTH anywhere

There is no such command in the AT command user guide …

you can see it in at command reference revision 4

Also you type it directly in evb

there is typing mistake in the AT command user guide rev 4
It should be like this:


 <auth_prot> Numeric parameter which specifies authentication protocol used for this PDP context   
                   
 0 --- None. Used to indicate that no authentication protocol is used for this PDP context.        
       Username and password are removed if previously specified. (default if omitted)             
                                                                                                   
 1 --- PAP                                                                                         
                                                                                                   
 2 --- CHAP

This will be corrected in the next version of AT command user guide
