Gary--

The following is excerpted from the Control Program Reference:
 
 Category 1, Function 63H - 
 Extended Query Bit Rate 

 
 This function returns the extended query bit rate in doublewords 
 for a bit rate greater than 19200 bits per second (bps). 

 If a general failure is not returned, the physical device driver 
 returns the bit rate values as defined. This function is extended 
 from the current Function 61H - Query Bit Rate. 


Hoping this clears things up a bit,
