Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

#define INCL_DOSDEVIOCTL
 
USHORT DosDevIOCtl(pusBaudRate, 0L, 0x0061, 0x0001, hDevice)
PUSHORT pusBaudRate;    /* pointer to variable for baud rate */
HFILE hDevice;          /* device handle                     */
 
The ASYNC_GETBAUDRATE function retrieves the baud rate for the specified
serial device. The baud rate specifies the number of bits per second that
the serial device transmits or receives.
 
Parameter    Description
────────────────────────────────────────────────────────────────────────────
 
pusBaudRate  Points to the variable that receives the baud rate.
 
hDevice      Identifies the serial device that receives the device-control
             function. The handle must have been created previously by using
             the DosOpen function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
