LiangChih,

What are the input and output terminators for the asyn port that is used 
to communicate with the moxa?  You can run these commands on the ioc shell:

   asynOctetGetOutputEos("PIE712")
   asynOctetGetInputEos("PIE712")

The output terminator needs to be '\n' when manually sending commands to 
the controller, but the output terminator needs to be empty for the 
driver to successfully communicate with the controller.  The driver 
appends the terminator to the commands that require it and omits it from 
the single-character commands, which don't use terminators.
