Ok, this is my first post to the net.....Lesse if this works...



Oh, and this is a ----PROGRAMMING PROBLEM---- abort if you aren't interested





Following is a short program I wrote that supposedly will send stuff to

the modem.  Kind of a Very Dumb Terminal program.  Everything seems to work

fine (the Modem Ready light comes on and when I type something the Send

light flashes).  But if I were to send ATZ or ATDT5551212, nothing happens.

The modem doesn't reset or dial or nutin'.



                    H E L P!!!!!!

extern struct MsgPort *CreatePort();

struct IOExtSer *mySerReq, *mySerWriteReq;

  LONG error, i;

  struct MsgPort *mySerPort, *mySerWritePort;

  BYTE *b, *c;

  char GetData[100], SendData[100];



  mySerPort = CreatePort("mySerial",0);

  if(mySerPort==NULL) exit(100);

  mySerReq = (struct IOExtSer *)CreateExtIO(mySerPort,sizeof(struct IOExtSer));

  if(mySerReq==NULL) goto cleanup1;

  mySerReq->io_SerFlags = 0;

  error = OpenDevice("serial.device",0,mySerReq,0);

  if(error !=0) goto cleanup2;



  mySerWritePort = CreatePort("mySerialWrite",0);

  mySerWriteReq  = (struct IOExtSer *)CreateExtIO(mySerWritePort,sizeof(struct IOExtSer));

  for(i=0;i<sizeof(struct IOExtSer);i++)

    *c++=*b++;

  mySerWriteReq->IOSer.io_Message.mn_ReplyPort = mySerWritePort;



  GetData[0] = '\0';

  while(GetData[0] != '*')

    {

    printf("Enter Text to Send to Modem...\"*\" to end\n");

    scanf("%s",&GetData);

    sprintf(SendData,"%s\n\000",GetData);

    WriteSer(SendData);

    }



  cleanup2:

    CloseDevice(mySerReq);

    CloseDevice(mySerWriteReq);

  cleanup1:

    DeletePort(mySerWritePort);

    DeletePort(mySerPort);

  }



WriteSer(modemdata)

  char *modemdata;

  {

  int error;



  mySerReq->io_Baud = 1200;

  mySerReq->io_StopBits = 1;

  mySerReq->io_ReadLen = 7;

  mySerReq->io_WriteLen = 7;

  mySerReq->IOSer.io_Data  = (APTR)modemdata;

  mySerReq->IOSer.io_Length = -1;

  mySerReq->IOSer.io_Command = CMD_WRITE;

  if((error = DoIO(mySerReq)) != 0)

    {

    printf("Serial.Device write error &ld \n",error);

    }

  return(error);

  }





Please, bear with me.  I am one of those "Teach yourself C" guys.  If it's a

stupid answer, please send it to me anyway!  All this is from the

oh-so-accurate CA books (first edition).  And I'm using a 1000 with a 2400

baud hayes-compat modem and 2 floppies (just in case anyone cares).





SORRY THIS IS SUCH A LONG POST!!!!
