Several years ago I wrote an application that used MSCOMM to retrieve data from a GPS device at 9600 baud.

The device has been upgraded and now uses 230400 baud but I when I try to set MSCOMM to 230400 I get an error "invalid property value." Is it possible to set MSCOMM to accept 230400? If so how do I do it?

Thanks in advance for any suggestions.
