putstr()

Hi,

CAn anyone point out what is the error is following code? It compiles OK, but doesnot work as expected.


code char* str1="xxyyzz";

void putstr(const char *s){
unsigned char ctr=8;
do{
tx_busy=1;
SBUF=*s++;
while(tx_busy);
}while(--ctr);

}

void main void()
{
...

putstr(str1);

..

}

'tx_busy' is a flag that is cleared from serial interrupt routine when it gets a tx-interrupt.

My serial port is working OK, if i use it as below, for example.

SBUF='X';

Any help would be appreciated.

Azra
