The Baud rate field offers a predefined set of values for good reasons. The available choices reflect the list of standard baud rates as mentioned in https://learn.microsoft.com/en-us/windows/win32/api/winbase/ns-winbase-dcb. Technically you just should be able to select other arbitrary baud rates. Pratically you are limited to those baud rates that the device driver can handle. To check, study the properties of your com port device in Windows Device Manager.
If you're really sure that your com port driver can do 28800 bps, you can easily clone this repository and have the neccessary option in our own fork.
