printf to the mplab "UART 1 OUTPUT" simulator outp

I found several topics on this forum about "mplab X and ccs compiler", but in no one I was able to find the solution for getting a ccs compiled program to printf to the "UART 1 OUTPUT" of the MPLAB X.

Same program (compiled with the Microchip XC) works very nicely redirecting the usart output to the mentioned MPLAB X window.

How can do same using the CCS C ????

Thanks in advance

Provided your code has the #use rs232 setup to talk to the hardware UART, it works.
The simulator con only simulate the hardware UART, so if you have configured a soft UART, it won't work.

with:
#USE RS232(UART1, baud=9600, stream=RS2321)

fprintf(RS2321,"Test string\r");

will print to the simulator.

You should have said what PIC in your first post.

If memory serves me right (it gets fuzzy once in awhile...), the 1709 has PPS in it, so you have to specify the pin to be the UART TX.
There is a 'sticky' up top to help with coding PICs with PPS.
