Hello. How can I determine the baud rates supported by my serial driver? My driver details (from the Device Manager) follow, but they do not seem very helpful. I am writing an application that is crashing because I am apparently attempting to to set COM1 to an unsupported baud rate, so I need to know which baud rates the driver does support. Any suggestions would be appreciated. Thanks.

Driver files:

C:\Windows\system32\drivers\serenum.sys

C:\Windows\system32\drivers\serial.sys

Provider: Microsoft Corporation File

Version: 5.1.2600.5512 (xpsp.080413-2108)
