Now I have read the manuals to figure out how to use Rpi miniCom to send an instruction to AX-12A. From now on we no longer use CM530, or any python program. We only use Rpi miniCom to send AX-12A commands (instruction packets), an hopefully receive replies from AX-12A.
Now the manuals: (1) CM530 Manaul
http://emanual.robotis.com/docs/en/parts/controller/cm-530/

(2) Robotis eManual
http://emanual.robotis.com/

(3) Dynamix instruction packet
http://support.robotis.com/en/product/actuator/dynamixel/communication/dxl_packet.htm
(4) AX-12A Manual
http://emanual.robotis.com/docs/en/dxl/ax/ax-12a/#control-table-of-eeprom-area

Now what you can try is the foillowing:
(1) Connect Rpi to AX-12A in full duplex mode,
(2) Use Rpi miniCOM to send an instruction packet, eg. Reset,
(3) miniCOM to read status packet.
(4) If 1 ~ 3 is OK. Then use the python loopback program (of course no chorting TxD and Rxd, but connect Ri to AX-12A in deuplex mode) to do 1 ~ 3.
Good luck and cheers.
