Type
XMSG_TG_PLAY_CMPLT
Direction
Outbound
Description
Tone Generator indicates the completion of playing tones.
Format
typedef struct{
XMsgHdr_t head;
/* message header */
UINT16
reason;
/* the reason of completion: */
/* XMSG_STOP_REASON_USER(1) */
/* XMSG_STOP_REASON_EOD(2) */
UINT8
numTones;
/* number of tones played. 0 if FSK data */
} XMsgTGPlayCmplt_t;
Macro
#define XMSG_FIELD_TG_PLAY_CMPLT(pMsg, rsn, num)\
{\
reason
= ((XMsgTGPlayCmplt_t *)(pMsg))->reason;\
num
= ((XMsgTGPlayCmplt_t *)(pMsg))->numTones;\
}
Type
XMSG_TD_RCV
Direction
Inbound
Description
Require Tone Detector to receive a tone string.
Format
typedef struct{
XMsgHdr_t head; /* message header */
UINT16 totalTimeout; /* total time out (in 10 ms unit) */
UINT16 firstDigitTimeout; /* first digit time out (10 ms uint)*/
UINT16 interDigitTimeout; /* inter digit time out (10 ms unit)*/
UINT16 termDigit; /* OR'd terminate digit bits */
UINT8 numDigits; /* number of digits to receive */
} XMsgTDRcv_t;
Macro
#define XMSG_MAKE_TD_RCV(pMsg, trans, inst, num, term, tm, fstTm, intTm)\
{\
XMSG_MAKE_HEAD(pMsg, trans, XMPR_TNDET, inst,\
sizeof(XMsgTDRcv_t), XMSG_TD_RCV, 0)\
((XMsgTDRcv_t *)(pMsg))->numDigits = num;\
((XMsgTDRcv_t *)(pMsg))->termDigit = term;\
((XMsgTDRcv_t *)(pMsg))->totalTimeout = tm;\
((XMsgTDRcv_t *)(pMsg))->firstDigitTimeout = fstTm;\
((XMsgTDRcv_t *)(pMsg))->interDigitTimeout = intTm;\
}
Response
Tone detector receives completed message (
XMSG_TD_RCV_CMPLT
)
