RS-232 missing characters

[Forest]

Anyone know why I always miss the last two characters off string printed to any terminal program??

Am using very minimal program to printf across rs-232. When i use the internal SCI Pins C6 and C7 the last two characters don't print. Works OK when i use Pins_A0 & A1 or when I put a while loop after the printf eg.
while(TRUE)
putc( getc()+1);

Am reasonably new to C and PICs - probably something I haven't spotted.


#include <16F877.h>
#fuses hs,nowdt,noprotect,noput,nowrt,nolvp,nobrownout
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)

main() {
printf("\r\nRead or Write: ");
printf("start");
}

The CCS compiler automatically puts a Sleep statement at the end of your code and the program is getting there before the USART has a chance to send the data. Add the following to the end of your main block and it should fix your problem:

while (TRUE) {}
