    2. Dos/windows 3.X two configuration software programs are provided with the dsp-200/300: a client driver, and a card enabler. Both of these programs are executed from dos (before entering windows) and allow operation of the dsp-200/300 in both the dos and windows 3.X environments. For optimal opera...

    H instructs the client driver to enable the rts-cts modem control handshake on the rs-422/485 port. When modem control handshaking in enabled, the 16c750 uart’s rts and cts signals are connected to the rs-422/485 auxiliary channel. The auxiliary channel may then be used for handshaking between the d...

    Furthermore, some systems use the high memory area for bios shadowing to improve overall system performance. In order for the enabler to operate, any bios shadowing must be disabled in the address range specified for the configuration window. Bios shadowing can usually be disabled through the system...
