USCI UART receive only one byte of two byte message, MSP430F5418A

Hello,

I've got a USCI UART on an MSP430F4318A connected to a Bluegiga WT12 (iWRAP v4 firmware) and whenever the device responds to a carriage return (0xD) or a newline (0xA) character sent to it, it spits out a 0xD and 0xA back (see o-scope shot at bottom, correct me if I'm reading it wrong, but I see a 0 start bit, then the LSB-first 8-bits of the first byte, then a 1 stop bit, then the same for the second byte of data) in a single 2-byte chunk (I'm sending just one at a time, and setting breakpoint on the UCA1TXBUF = 10;).  I'm concerned because I can only ever see the second character in the MSP430 as the second char immediately overwrites the first one (setting UCOE when this happens, as it should).  My question is, is there any way to get both characters?  I had figured with a fast enough clock (16MHz SMCLK) my ISR would go fast enough to get them both.  Has anyone successfully communicated with a WT12 using an MSP430?  My code is below:

// setup code for UART
    P5SEL |= (BT_RX | BT_TX);
    // port speed at startup is 115200 bps
    UCA1CTL1 |= UCSWRST;                      // **Put state machine in reset**
    UCA1CTL1 |= UCSSEL_2;                     // SMCLK
    UCA1BR1 = 0;
    UCA1BR0 = 8;
    UCA1MCTL = UCBRS_0 + UCBRF_11 + UCOS16;
    UCA1CTL1 &= ~UCSWRST;                     // **Initialize USCI state machine**
    UCA1IE |= UCRXIE;

// code inside main while() loop

while (!(UCA1IFG&UCTXIFG));
while ((P1IN&BT_RTS));               // doesn't do anything
UCA1TXBUF = 13;

// ISR code

#pragma vector=USCI_A1_VECTOR
__interrupt void USCI_A1_ISR(void)
{
  switch(__even_in_range(UCA1IV,4))
  {
  case 0:break;                             // Vector 0 - no interrupt
  case 2:                                   // Vector 2 - RXIFG
    // note family users guide recommends (p902) checking stat for UCOE, then reading, then UCOE again
    //if(UCA1STAT & UCOE == 1)                     //check if UCOE is still high
    if (uart_rxchars<256) { datarx[uart_rxchars++] = UCA1RXBUF; }
    else
    {
        // set overflow condition, de-assert CTS
        // P1OUT |= BT_CTS; // doesn't work, WT12 ignores this...
        uart_rxchars=0; // wrap around the ring buffer
    }
    break;
  case 4:break;                             // Vector 4 - TXIFG
  default: break;
  }
}
