Configuring the COM Port
Select the PCI Serial Port you want to configure (for example COM3) by right clicking the
mouse, then click “Properties”.
Click the “Port Settings” to configure the Bits per second, Data bits, Parity, Stop bits and
Flow control if you need to adjust the settings.
Notes:
Click the “Advanced” if you want to set more advanced features.
There are three kinds of flow control: Xon/Xoff, Hardware and None. Xon/Xoff uses a
software protocol, Hardware flow control uses RTS/CTS, but the RTS/CTS is controlled by
software. None means there is no flow control.
Configure the “Enable Auto CTS/RTS Flow Control”, “16/32/64 bytes FIFO length”, and
Receive/Transmit Buffer trigger level if you want to change.
The 128K software FIFO adjusting only supports Microsoft Windows 2000 / XP / 2003 OS.
You can change the FIFO size and COM port number as needed.
