Hi developers,
I`m trying to make a communication (serial
communication) between palm and PC, but the words sent
are received by PC(hyperterminal) in diferents
characters. The code used to make the communication is
presented below:
static Err OpenSerial(void)
{
Err err;
SerSettingsType settings;
/* UInt16 flagsSize = sizeof(flags); */
/* SerControl(refNum, serSetSettings, &flags,
&flagsSize); */
err = SysLibFind("Serial Library", &refNum);
if(err==0)
{
err = SerOpen(refNum, 0, 9600);
switch (err) {
case errNone:
break;
case serErrAlreadyOpen:
SerClose(refNum);
FrmAlert(SerialBusyAlert);
return err;
break;
default:
FrmAlert(SerialOpenAlert);
return err;
break;
}
}
gConnected = true;
settings.flags = 0;
settings.flags = serSettingsFlagBitsPerChar8 |
serSettingsFlagStopBits1;
SerSetSettings(refNum, &settings);
return err;
}
static void WriteSerial(void)
{
Err error;
FormType *form = FrmGetActiveForm();
FieldType *field;
MemHandle h;
int i;
if (gConnected == false) return;
field = FrmGetObjectPtr(form,
FrmGetObjectIndex(form, MainNameField));
h = FldGetTextHandle(field);
if (h) {
Char *s;
s = MemHandleLock((void *)h);
SerSend(refNum, s, StrLen(s), &error);
if (error)
FrmAlert(SerialSendAlert);
MemHandleUnlock((void *)h);
}
}
static void CloseSerial(void)
{
Err error;
/* error = SerSendWait(refNum, 1000); */
/* ErrNonFatalDisplayIf(error == serErrBadPort,
"SrmClose: bad port"); */
/* if (error == serErrTimeOut) */
/* FrmAlert(SerialTimeoutAlert); */
SerClose(refNum);
gConnected = false;
}
What do you think about the error? Is the error
associated with baud rate?
