OK.  Can you try this:

Create a new write.c file, and put the following into it.  Don't
forget to add it to your project tree.





#include <p30fxxxx.h>
#include <stdio.h>

#define	SPEN	0x8000u
#define	TXEN	0x0400u
#define	TRMT	0x0100u
#define	TXBF	0x0200u
#define	RCDA	0x0001u

int write(int handle, void *buffer, unsigned int len)
{
	int i;
	
	switch (handle)
	{
	case 0:
	case 1:
	case 2:
		if ((U2MODE & SPEN) == 0)
		{
			U2BRG = 0;
			U2MODE |= SPEN;
		}
		if ((U2STA & TXEN) == 0)
		{
			U2STA |= TXEN;
		}
		for (i = len; i; --i)
		{
			while (U2STA & TXBF);
			U2TXREG = *(char*)buffer++;
		}
		break;
	default:
		break;
	}
	return(len);
}
