i386ex board console



I :
we found no response from i386ex target, when I run 
' vi console</dev/ttyS0 '.
below  something I do for get message from target on host linux. 
console:
 target com1 --- host com1 with 3 connect pins ( transfer,receive and grand)
 I use stty & setserial :
stty 9600        result: speed 9600 baud;line=0; -brkint --imaxbel
setserial       result: /dev/ttyS0 ,UART :16550A,port:0x2f8,IRQ:4
------
we developed a rom monitor for i386ex target:
address space for monitor :
          + ------------+  0x3ffffff
          |                   |  monitor code
          +-------------+ 0x3f80000
          |                   |  invalid space
          +-------------+ 0x0100000
          |                   | monitor running space
          +-------------+ 0x00f0000
          |                   | reserved 
          +-------------+0x000000
address space rtems for debug:
          +-------------+0x0000
          |                   |  initialized data 
          +-------------+ 
          |                   |  bss
          +-------------+ 
          |                   |  stack
          +-------------+
          |                   |  heap
          +-------------+
          |                   |  workspace
          +-------------+0x0c0000
          |                   |  code 
          +-------------+0x0f0000
in console.c: Set the BSPConsolePort to BSP_UART_COM1               
in bsp.h : #define RAM_END   0xC0000
we use exception 0-16 for monitor,not install raw IRQ 0-16 in rtems. 
--------------
Another question involved with this changing is the thread wake up is invalid whatever set breakpoint at timer ISR.
I found the level = 12870 , when I set breakponit at _ISR_Flash( level ) in _Watchdog_Insert(). Is there a problem of this value?
----
Any help/suggestion/guess/comment  on these problems will be 
highly appresiated.
