Data Rate - 1X or 4X Clock Speed
The 3PCIO1 port in the Device Manager has Data Rate, Clock
Speed settings for 1X or 4X.
Speed settings for 1X or 4X.
The 4X position provides a compatibility mode for software which
requires it. In the 4X position, all standard baud rate settings are
multiplied 4 times. For example, if the software sets 57.6K baud, the
actual baud rate will be 230.4K baud, 115.2K becomes 460.8K.

Refer to Specifications in Chapter 1 for baud rates available.
In many systems, faster baud rates can improve throughput
significantly. Actual throughput and faster baud rates are only
proportional if the system can keep up with the communications,
otherwise increasing the baud rate effectively only increases the idle
time between characters.
