6.The QSC(LP)-100 serial ports are also listed under the group Ports (COM and LPT). Windows 95 does not assign COM1-COM4 to ports addressed at nonstandard locations. The QSC(LP)-100 ports will be enumerated starting with COM5 (or higher) even if lower logical numbers are available.

7.Select any of the Quatech Serial Ports listed under the group Port (COM and LPT) and click the "Properties" button. This action opens a properties dialog for the specific COM port on the QSC(LP)-100.

8.Click the "Port Settings" tab and then click the "Advanced" button. The QSC(LP)-100 driver will display a custom Advanced Port Settings control, which allows the ports UART compatibility mode and FIFO threshold levels to be configured. The threshold values of full-scale for the transmit buffer and 3/4-scale for the receive buffer shown below are optimal for most applications. Note that the FIFO option for each of the QSC(LP)-100's two ports is configured independently.
