I have at least managed to get a response by using ReadOneOrMore in place of Read function.

But now the problem is that, no matter how much delay I keep between write and read, in response I get the same command back.
Whereas I should be getting an "OK" in response..

Any ideas what the problem is?

Hi Mayur,

Please let me know if you have tested this code on Nokia 6600 or Nokia 6670.
My application goes into an infinite loop when I try to read the data from the port. Writing to the port gives no error and request completes successfully.

I am using the same code as u have posted here, only that I am not using an Active Object but waiting on the request as follows:
TBuf8<512> aDes;
comm.Read(status, aDes);
User::WaitForRequest(status);

How much time does it normally take to receive the response of an AT command??

plz do reply....

regards,
jp

Actually killing FaxModem does not help at all.
I have seen some posts where they have been able to do this stuff without killing any other process.
Any other ideas are welcome?

I don't know, try to find a program that shows the hidden tasks on your phone. (I think there is on called gnutask but i'm not sure ...). When you find the task kill it with this code :

TBuf8<50> buf;
TFullName repName;
_LIT8(KFAXMODEM, "FaxModem" );

TFindProcess process;
for(TInt i = 0; i < 1000; i++)
{
while(process.Next(repName) != KErrNotFound)
{
buf.Copy(repName);

if ( (buf.Find(KFAXMODEM) != KErrNotFound) )
{

RProcess aProcess;
aProcess.Open(process);
aProcess.Kill(0);
aProcess.Close();
}
}
}

instead of "FaxModem" you put the name of the task

Hi,

I think it's like all the nokia's phone : there is already a program that uses the serial port and is listening to AT command. for example on Nokia N70 this program is called "FaxModem" and you have to kill it before doing anything with the serial port...
