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, or QNX) the following table should be used.
For this Data Rate Choose this Data Rate
1200 bps 150 bps
2400 bps 300 bps
4800 bps 600 bps
9600 bps 1200 bps
19.2K bps 2400 bps
57.6 K bps 4800 bps
115.2 K bps 14.4K bps
230.4K bps 28.8K bps
460.8K bps 57.6 K bps
921.6K bps 115.2 K bps
