Subject: Debugging message through FDC37C672-COM of MBX860??

Hello,
I'm so sorry about this question.
I want to print out debug messages to console monitor from the
application loaded at MBX860 through EPPC-Bug. I was supposed to use
EPPC-Bug's system call for this purpose. But it wasn't possible because my
application overlap
all exception codes and stack. And then I tried to use SMC1 or SMC2's UART
for this purpose. But it's not working.
The port status is the following.
------------------
EPPC-Bug>pf
Current Port Assignments: (LUN: Device-Name Port-Name)
00: FDC37C672-COM COM1 (Console)
01: MPC8XX-SMC SMC2
02: MEMORY CHNL0
------------------------
According to MBX manual, SMC1 is used as console port.
If it's true, COM1 is using SMC1?
So, I thought I must use SMC'1 UART to print out to a console. Is it
correct?
I tested the application using SMC1' s UART
by applying a SMC's UART application note provided by Motorola's
website(MPC860COD17).
But It doesn't seem to work. I can't see anything from a console after
executing this test application.
Thank you any help.
