### ASYNC_GETBAUDRATE (61h) - Remarks

If a general failure error is not returned, the physical device driver returns the current bit rate of the COM device.

Note: If this function is called when the current bit rate setting of a COM port is greater than what can be stored in a 1-WORD field, the device driver sets the bit rate to 1200 bps (default value) and returns 1200 bps to the user.
