Can't receive on UART using MCB2140

Hello folks. I am attempting to test serial comms on the MCB2140. While I have tested transmit with strings and single characters, I have yet to get coherent data from a device into the LPC2148.

Here is the current, simple program I am using, modified from examples found on Keil's website.

#define CR     0x0D
#include <LPC21xx.H>

void init_serial (void);
int putchar (int ch);
int getchar (void);


unsigned char test;

int main(void)
{
init_serial();

while(1)
{

putchar('?');                                           //checks for working output
putchar(getchar());                                     //Echo terminal
}
}

void init_serial (void)                   /* Initialize Serial Interface       */
{
  PINSEL0       = 0x00000005;         /* Enable RxD0 and TxD0              */
  //PINSEL0     = 0x00050000;         /* Enable RxD1 and TxD1              */
  U0LCR         = 0x00000083;         /* 8 bits, no Parity, 1 Stop bit     */
  U0DLL         = 97;         /* 9600 Baud Rate @ 15MHz VPB Clock  */
  U0LCR         = 0x00000003;        /* DLAB = 0                          */
}


int putchar (int ch)                      /* Write character to Serial Port    */
{

  if (ch == '\n')  {
    while (!(U0LSR & 0x20));
    U1THR = CR;                    /* output CR */
  }
  while (!(U0LSR & 0x20));
  return (U0THR = ch);
}


int getchar (void)                              /* Read character from Serial Port   */
{

  while (!(U0LSR & 0x01));

  return (U0RBR);
}

Upon running, I see a question mark, like I expect, but no further data.
I have a straight cable plugged into UART0, and hyperterminal configured for 9600 8N1. I also tested this on some old black box serial device, but had no better results.
I expect it to wait for input (it does) and echo back from the hardware whatever key I send.
Anyone able to help offer insight into the situation as to why I cannot receive?
