Figure 3. DOS Client Output Driver Options.

Hinstructs the client driver to enable the RTS-CTS modem control handshake. When modem control handshaking in enabled, the 16C550 UART’s RTS and CTS signals are connected to the RS-422/485 auxiliary channel (AuxOut and AuxIn). The auxiliary channel may then be used for handshaking between a DSP-200/300 RS-422/485 port and a peripheral device. When modem control handshaking is disabled, the RTS and CTS signals from the 16C550 UART are looped back to each other. If this option is omitted, the default setting is RTS-CTS modem control handshake disabled. See the Hardware Information section for more information.

Uinstructs the Client Driver to disable the QSP-200/300's interrupt status register and enable the Scratchpad registers of the individual UARTs. This option is only required in very rare cases where an application program requires access to the UART's Scratchpad register. If this option is omitted, the QSP-200/300's interrupt status register is enabled and the UARTs' Scratchpad registers are disabled.
