Cellular Result Codes +CRC
Description: 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 for asynchronous transparent
+CRING: REL ASYNC for asynchronous non-transparent
+CRING: VOICE for normal speech.
Values:
0 Disable extended reports
1 Enable extended reports
Syntax: Command syntax: AT+CRC=
Command Possible responses

DTE-DCE Local Rate Reporting +ILRR
Description: This parameter controls whether or not the extended-format “
+ILRR:” information text is
transmitted from the DCE to the DTE. The 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).
Values:
0 Disable local port rate report
1 Enable local port rate report
Can take the following values: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
