Syntax:
This command shows more detailed ring information for an incoming call (voice or data). Instead of the
string “RING”, an extended string is used to indicate which type of call is ringing (e.g. +CRING: VOICE).
These extended indications are:
+CRING: ASYNC
+CRING: REL ASYNC
+CRING: VOICE
<mode>
Command syntax: AT+CRC=<mode>
This parameter controls whether or not the extended-format “+ILRR:<rate>” information text is
transmitted from the DCE to the DTE. The <rate> reported represents the current (negotiated or
renegotiated) DTE-DCE rate.
If enabled, the intermediate result code is transmitted in an incoming or outgoing data call, after any
data compression report, and before any final result code (CONNECT).
<rate> Can take the following values: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
