Dear sterretje,
thank you very much for your reply.
Sample data
'.';
'E';
'P';
ACK;
'5' ;
'G'; .
'A';
'B';
NUL;
'1';
'4'; Check sum
EOT;
For example from the above data when Micro- processor receives ACK Character , it will send message to PC I have identified “’ EP’ YOU CAN SEND THE DATA ”
IF (REC_ARRAY*==EOT)*
{
IF (ACKNOWLEDGE==TRUE){
SERIAL.WRITE(“OK”);
}
}
hope my understanding is correct.
