Seial Communication Delay

Hi Guys, I m working on a project , where i am using Arduino Due Native Port(SerialUSB) for Serial communication.I write only one character on the SerialUSB and receive a character from the system instantly.The timing i am measuring using micros() function.It is observed that it takes almost around 90 to 100ms for the data to be received.And further it is not consistent also. Does that mean that the SerialUSB is really taken so much time to read 1 byte of data?Then why is it not consistent. In order to make max speed i am using the baud rate of 115200.Still it has no effect. To crosscheck i used a RS 232 Board and used Serial1 .Still it too has no effect. Can you please suggest something in this.

I suggest that you post your code.

I suggest you stop posting the same question in different parts of the forum.

How can that be? The OP appears to have only 1 post ?
