• Octet 6 contains a value with bit 7 equal to one. Bits 6 through 0 (000 0010) of this octet are combined with the base
pointer value. The resulting sixteen bit value '0532' is the UCS2 Armenian character ‘capital BEN’.
• Octet 7 contains a value with bit 7 equal to one. Bits 6 through 0 (001 0011) of this octet are combined with the base
pointer value. The resulting sixteen bit value '0583' is the UCS2 Armenian Character ‘small PIWR’.
• Octets 8 and 9 are processed in a manner similar to octet 5. The values in this example correspond the characters
dash ‘ - ‘ and ‘ 1 ’.
Commands Over DM Port (MuxLite)
This functionality provides the ability to send a limited set of AT commands to the Q24x8 module over the diagnostic port.
Referred to as MuxLite, this functionality is only available during a data call. The use of this functionality requires a host
application capable of processing the HDLC protocol described in the MuxLite application note [13].
The diagnostic port is normally used for the transmission of unsolicited diagnostic messages during module operation. The
MuxLite feature adds the supported AT commands and responses to this existing diagnostic message data stream. The host
application is required to extract the AT command response data from the diagnostic message data stream.
The following table summarizes the AT commands that are currently supported by the MuxLite feature. Refer to the
appropriate section in this manual for command usage details. Note that the parameter range display variation (=?) of these
commands (e.g. AT+WSTR=?) are not available using MuxLite and will result in ERROR. With the exception of +CLCC, all AT
commands in this table will result in ERROR if used with MuxLite and a data call is not active.
MuxLite Supported AT Commands:
Command Description
AT+CLCC List current call state. Note: This is the only command that is not active data call
dependent. It can be used at any time on the diagnostic port.
AT+WSTR Wavecom status request
AT+CSQ Signal quality
AT+CNMA SMS message acknowledgement. This message will be acknowledged when
accepted for processing. The resulting data will be returned in a separate unsolicited
response.
AT+CNMI SMS new message indication
AT+CPMS Used to select the message storage area used by the +CMGR command. The “MT”
area holds received SMS messages.
AT+CMGR SMS read message. This message will be acknowledged when accepted for
processing. The resulting data will be returned in a separate unsolicited response.
AT+CMGS Send SMS message. Two HDLC packets are required. The first packet must contain
the SMS message destination data (everything up to and not including the <cr>
character in the normal +CMGS command). The second packet must contain the
SMS message text; Unicode is supported. The +CMGS control characters (<cr>,
<ctrl-Z>, and <ESC>) are not required and ignored if included. Do not send any other
HDLC packets between the two +CMGS packets.
AT+CMGD Delete SMS message
AT+CCED Cell environment
AT+CREG Registration and roaming
Unsolicited Messages General unsolicited status or indication messages from the module.
