Hallo allemaal, I first wanted to ask why on the C64 UNTALK is sent with ATN = (L) and UNLISTEN isn't. Please see from $EDEF on. But then I noticed the JSR $ED11 at $EE00. $ED11 first checks if there is a byte in the queue and, if so, sends it first. Then it sets ATN (L) and sends the command byte. So setting ATN = (L) at $EDF3 isn't needed anyway IMHO. But what will happen now if a TALK needs to be sent and there is still a byte in the queue? This byte will be sent with ATN = (L) and IMHO will confuse the attached device ????
