SYMPTOMS
After you manually define a baud rate for one of the communication ports (COMx, where x is the number of ports on your computer) in Control Panel by typing in the baud rate value, the baud rate is changed to first value on the drop-down list, which is 75. For example, if you define the COM1 port to a baud rate of 28800, the next time you select Settings in the Ports dialog box, the baud rate is changed to 75.



WORKAROUND
To work around this problem, select an already-defined baud rate in the drop-down list.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
