We are attempting to run some 16-bit software which ran nicely under
Win98SE, but fails to communicate with Com 1 under WinXP Pro SP2. We get the
message in a command prompt window in a dialogue box titled MS-DOS
Subsystem, "Driver doesn't support baud rate (9600). Close Ignore" We've
tried several baud rates with the same result. Each time we configured the
com1 port in Device Manager for the intended baud rate.

I don't find anything in the Resource Guide about this. Anyone have any
ideas about what we can do?

Hi,

You should check with the software distributer for assistance. By the by,
WindowsXP does not support 16-bit programs that attempt to directly address
the system hardware. Software needs to pass hardware instructions to the
operating system.

What is the program you are trying to run?

robert roland

My guess is that your application is programmed to access I/O
registers directly, and not through Windows' API calls, as it should.
Windows 98 allows such direct hardware access, but XP does not.

The obvious solution is, of course, to upgrade the software to proper
32-bit design, but that may not be a possibility for you?

You might try to install '98 on a virtual machine and see if VMware's
hardware emulation can handle your situation.

The program is a C8051 compiler for the Dallas cpu by Kiel and they do not
provide an upgraded version for this particular CPU..

Okay we can try that, just a minute... Well it doesn't work but I get a
different message, simply, "cannot communicate with port 1". This is a
standard Keil message. And no, we can't get a 32bit version of this
particular complier. Any other thoughts?

Are you referring to a program from this site, http://www.keil.com/ ? I
did not see a program that would run under WinXP. I might have some
suggestions if I knew exactly what you were trying to do.

On a second look I did find this.
Keil Evaluation software
"Your computer must meet certain minimum system requirements for the
evaluation software to function properly.

* Windows 98, Windows NT Version 4, Windows 2000, Windows XP
* Mouse or Similar Pointing Device
* 30 Megabytes Free Hard Disk Space
* 128 Megabytes of RAM"

So if I'm looking at the correct company, your software should run. Have
you checked with Keil product support?

Did you remember to map the virtual COM port to a physical one?

No, how does one do that?
