--- you are not assigning the Mvar registers in order as you think... there are 5 extra registers in the middle... change you addressing so they are all in sequence
M0->Y:$3600,0,8
M1->Y:$3601,0,8
M2->Y:$3602,0,8
M3->Y:$3603,0,8
M4->Y:$3604,0,8
M5->Y:$3605,0,8
M6->Y:$3606,0,8
M7->Y:$3607,0,8
M8->Y:$3608,0,8
M9->Y:$3609,0,8
.... here are the 5 0 bytes... they are between 3609 and 3610
Y:$360A
Y:$360B
Y:$360C
Y:$360D
Y:$360E
M10->Y:$3610,0,8 change this to 360A
M11->Y:$3611,0,8 change this to 360B
M12->Y:$3612,0,8 change this to 360C
M13->Y:$3613,0,8 change this to 360D
Oops！I have made the elementary mistake, the address is a HEX number. thanks a lot, @Unit101! You have done me a great favor.

Hello everyone:
I'm using a turbo PMAC2 CPU, and I have a serial devices need to interface with the delta tau(receive some HEX data from PMAC).
The problem happened as follow:
I'm trying to a set of HEX numbers like "00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D"(14 numbers in total)，all these values are assigned to the M-variables from M0-M13, the PLC program are listed blow.
--------Begining of the program-------
CLOSE
I52=5 ;Basic setup to enable auxiliary serialport
I53=15 ;Baud rate is set to 115200
I1 = 1
I43 = 3
M100->X:$FFFFE1,24 ;The number of bytes to output
M101->X:$FFFFE3,24 ;Starting address to send
M102->X:$FFFFE0,23 ;bit 23 of X:$FFFFE0 must be set to 1 to enable the output
M0->Y:$3600,0,8
M1->Y:$3601,0,8
M2->Y:$3602,0,8
M3->Y:$3603,0,8
M4->Y:$3604,0,8
M5->Y:$3605,0,8
M6->Y:$3606,0,8
M7->Y:$3607,0,8
M8->Y:$3608,0,8
M9->Y:$3609,0,8
M10->Y:$3610,0,8
M11->Y:$3611,0,8
M12->Y:$3612,0,8
M13->Y:$3613,0,8
OPEN PLC1 CLEAR
M0=$00
M1=$01
M2=$02
M3=$03
M4=$04
M5=$05
M6=$06
M7=$07
M8=$08
M9=$09
M10=$0A
M11=$0B
M12=$0C
M13=$0D
M101=$3600
M100=13
M102=1
DISABLE PLC 1
CLOSE"
------End of the program---------
But I received a string "00 01 02 03 04 05 06 07 08 09 00 00 00 00", then, I changed the value of "M100" to "19", and I received a string "00 01 02 03 04 05 06 07 08 09 00 00 00 00 00 0A 0B 0C 0D 00", I'm curious about this output, why does five 0 Byte appear? anyone could tell me what happened? Thanks a lot!
Problem in writting auxiliary port

Hello Unit101, sorry to disturb you again, I'd like to know whether PMAC send bytes one by one to serial port, or all bytes at one shot. Thanks for your time!
