UART DATA TRANSFER PROBLEM

I am using USB -TTL-5V cable to work with MKE02Z64VLC chip. Mine receiver on interrupt only receiving one character. Should I toggle CTS pin to receive rest of characters?

void AS1_OnRxCharExt(AS1_TComData Chr)
{
/* Write your code here ... */
word Received;
//byte err = 0;
(void) AS1_RecvBlock((byte*) &rx_message.RxBuffer, RX_DATA_BUFF_SIZE, &Received);
}

Due to different received data length I need to detect last character '\0'.

Problem finally was solved, as: while using only Internal oscillator it can not be adjusted for standard baud rate. Just use whatever it gets, i.e. 58308.

New code looks like this see attachment.
