Yokogawa UT37 Temperature Controller Communication Interface.

Yokogawa UT37 Temperature Controller Communication Interface.

(OP)
Hi all, I need your help for information.
Currently I have a DOS base communication interface with Yokogawa UT37 temperature controller, using C++ programming language.
My question is, I had search for this kind of communication interface for Windows NT 4 base, but still cannot get it. Do I need any driver or library to install into Windows NT 4 for communication interface?? I found that DOS base communication interface are using RS485 COM Port, but i also found that the program had include moxa-cl.obj library file. It make me confuse to continue to modified from the DOS base program to Windows base program.  Please advice me if you know any method of writing a source code for this temperature controller communication interface.
P/S: I am using Visual C++ 5.0 to write the program. Thanks.

RE: Yokogawa UT37 Temperature Controller Communication Interface.

Your problem description is not complete.

1. It seems that you have a special I/O card with a RS485 port on your PC.  Is it?

2. The DOS program seems to use a special object file, moxa-cl.obj, while linking.  Do you have that file?

3. Windows NT does not permit direct hardware access.  There is a way to fool the OS, though.  Techniques used in the DOS program may not work in NT at all.

Feel free to contact me over email.

Cheers
Rahul
