Baud Rates and Oscillator value
The following table shows some common data rates and the rates you should choose
to achieve them when using the SIO-485.LPCI. If the O/S of choice is Windows
95/98/ME/2000/NT/XP, the oscillator value (14.7456 MHz) should be entered into
the 'Advanced Tab' on 95/98/Me/2000/XP Device Manager applet. Typically this is
done automatically when the Sealevel Software driver is loaded.
When using Windows NT, the 'Advanced Ports' applet in the Control Panel should
be launched and the oscillator value entered manually in the 'Advanced' tab, or all
data rates will be eight (8) times the selected rate. For example if a data rate of
19.2Kbps is selected, the actual data rate will be 153.6Kbps.
When using any other OS (i.e. Linux) the following table should be used:
If your communications package allows the use of baud rate divisors, choose
the appropriate divisor from the following table:
