6. The DSCLP-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 DSCLP-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 DSCLP-100.
8. Click the "Port Settings" tab and then click the "Advanced" button. The
DSCLP-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 DSCLP-100's
two ports is configured independently.
