Description: Gets the storage base of SIM messages.

Input: <fd> the cellular modem

Return Value: 0: on SIM card, 1: on modem module, 2: on both, otherwise, the function fails

int cellular_modem_sms_get_message_count(unsigned int fd, int *maximum);

Description: Gets the number of stored messages allowed out of the maximum space.

Input: <fd> the cellular modem

Output: <maximum> pointer to the maximum number of messages allowed

Return Value: The number of stored messages; otherwise, a negative value indicates a failure

int cellular_modem_sms_send_message(unsigned int fd, unsigned int msg_mode, SMSMSG

*psms);

Description: Sends an SMS message to a specific phone number.

Remarks:

#define MAX_SMS_BYTES 512

typedef struct _SMSMSG

{

unsigned int been_read;

char msg_date[12];

char msg_time[20];

char phone_number[20];

unsigned int msg_length;

char msg_text[MAX_SMS_BYTES];

} SMSMSG, *PSMSMSG;

To use PDU mode to send your SMS messages, you must specify the exact length in “SMSMSG.msg_length”

in the SMSMSG data structure.
