Got it working.
I added the highlighted line in serial_lld.c and it enables the RTSEN bit.

#if LPC17xx_SERIAL_USE_UART1
if (&SD2 == sdp) {
div = LPC17xx_SERIAL_UART1_PCLK / (config->sc_speed << 4);
LPC_UART1->MCR |= 0x40;
}
#endif

My pin configs are set for RTS and CTS and using a scope I can see my data when I transmit, but I get no response from the other devic...
