reception RS232 with interruption

[joseph]

Hello,

I've got a problem. I want a script who answer when a RS232 transmission what detected with a interruption. This answer will be a another RS232 transmission. .....

But no answer.... please read my script and tell me what please .

#include <16F877A.h>
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7,PARITY=O,STOP=1)

//----------------------------------------

#int_rda
void interruption()
{
PUTC(0x10);
}

//------------------------------------

void main (void)
{

enable_interrupts(int_rda);
enable_interrupts(global);
}

Two things.
You _must_ terminate the 'main', with something like a:

while(true) ;

Otherwise the processor runs off the end of the code, and goes to sleep. Once this has happened, it won't respond to the serial.

Then you really need to read the received character in the interrupt. Otherwise after two characters, the UART will hang, and receive will stop working. A simple 'getc', will d this.
