jacekd Posted November 3, 2004 Report Posted November 3, 2004 DLE has ASCII code 10hex. And that's the way it is. Cannot be changed. Quote
Guest micmez Posted November 3, 2004 Report Posted November 3, 2004 so if i'm receiving 15 , what does it mean ? is it an error code or a kind of rejection etc ? Quote
jacekd Posted November 5, 2004 Report Posted November 5, 2004 15hex is NAK. Meaning depends when you get it. After sending STX (handshake) it means receiver not ready. During data transmission (possible reason - wrong parity) or after transmission (possible reason - wrong BCC) - transmitter should repeat transmisson. Quote
