Two questions: Does anyone have additional information on the TALK ATN turnaround part of the IEC protocol? The PRG doesn;t really explain it to me (it looks like it must occur after a cmd byte, but is it always TALK? Can it be TKSA?) As for codes, I see x24 to x32 is LISTEN x44 to x52 is TALK x5F is UNTALK x3F is UNLISTEN xFX is SECOND (LISTEN) Not sure what TKSA is (04 - 12?) Anyone know? When I do open15,8,15,"i":close 15 I get: c28 cFF d49 c3F c28 cEF c3F I understand the TALK 8, SECOND 15 'I', and the followup TALK 8, but what is EF? The 3F I get, but does EF mean END or something?
