COM1 not work

I build the win ce 5.0 image with serila port support but my com1 does not
work.
is there any way to enable com1 ?
Thanks

Yes, call BIOS Setup!

And make sure of it, the plug is inserted on Com1 port.

The COM1 on my mini2440 not works.
The COM ports of my computer are working.
i write a program to test com ports of mini2440.
when i want to open the com1 on Mini2440 it returns an error.
but all other ports are function properly.

When i run my program on mini-2440 it says "COM1 does not exist"

i check NOSERIAL and KITL UART but the problem is still exits.

any one can help me ?

Com1 and COM1 are different names.
C++ is case-sensitive.
Maybe this will help you further!

Monitored once the variables in the debugger.
When reading the source code is overlooked quick little different spelling.

You will have to use COM port using specific names such as "ASRL1::INSTR".

Right!
You can also include more than redirect to 'COM1' or whatever.
These are experiences that I often do myself. 
Because ultimately, even when you know what, in the source code is
available.
