Don't understand why you want to do such a lower-level thing. I have no idea how to do it. I guess you need use JNI.

So, It's really easy in VC++, I just finished this staff, but boss ask me if we can move this staff thing to Java.

Sorry, I do not exactly how to do it. However, I can assure you that
Java Native Interface be required here because your task is platform -dependent.

You can't and needn't to implement COM port coding in Java, just write it in c.And you can use CORBA to invoke C coding if you want to migrate your software to Java.

I agree the first part - write code in C

It does not make sence using CORBA to access this small piece C code only to access the COM1 port.
I agree with Jabber that JNI should be used.
But the whole idea sounds like crazy. Why Java and the COM1 together?
If you can treat the COM1 like a character stream (like in BASIC) you may possiblly use File/StreamReader to access the DOS device COM1 for read/write. But the quality of service may not be garanteed.
There's an individual package of Java2 Platform, it supports platform independent communications. For detail, go to http://java.sun.com/products/javacomm/ , GOOD LUCK!
