Try to programme Maxtrac (D45MQA5GB5AK) with ribless programmer (genuine Motorola, AARKN4081B), but RSS report me that cant initialize seiral bus (error 5).
Serial port is correct. Connection to PC via D-sub 25 pin to D-sub 9 pin adapter (tested). I try under Win 98 and Win 98's DOS mode. Soft is RVN-4043-S (R05.07.03). Pinout of 8 pin connector (Maxtrac) and 10 pin connector (CDM series), the same.
May be this error happens because of short plug benween 4 & 11 pins does not exist in ribless programmer (I check it - really no short!)?

This short plug is critical in this case?
In any case I can not short this pins, because my PC have 9 pin serial port and I must use D-sub 25 pin to D-sub 9 pin adapter to plug specified ribless programmer. And as result pin # 11 become disconnected from everywhere, because this pin unassigned inside of adapter.
Any ideas?
