Baud Rates and Divisors for the ‘Div1’ mode
The following table shows some common data rates and the rates you should choose to achieve them if
using the adapter in the ‘Div1’ mode. Windows 95/98/ME/2000/NT/XP defaults the oscillator value to
1.8432 MHz (Div4). This is suitable for traditional serial communication needs and provides for a maximum
data rate of 115.2 Kbps. The oscillator value 7.3728 MHz (Div1) may be entered into either the ‘Advanced
Tab’ on 95/98/Me/2000/XP Device Manager applet or in the ‘Advanced Ports’ applet in the NT Control
Panel. This will allow easy selection of typical baud rates up to the maximum data rate of 460.8Kbps.
