User`s manual

2.1.2.4 Example 4
DEVICE = C:\DSP-200\DSP230CL.SYS(i5,h,b300)
In example 4, a single command line argument is provided. Because the parameter
order is not significant, the Client Driver will attempt to configure a DSP-200/300
inserted into any socket with a base address of 300H and IRQ 5. If address 300H or
IRQ 5 is unavailable, the DSP-200/300 will not be configured. If the Client Driver can
successfully configure the DSP-200/300, the RS-422/485 output drivers will always be
enabled, and RTS-CTS modem control handshaking will be enabled on the RS-422/485
port’s auxiliary channel.
2.1.2.5 Example 5
DEVICE = C:\DSP-200\DSP230CL.SYS (b300,i5) (i10) ( )
In example 5, three command line arguments are provided. The Client Driver will first
attempt to configure a DSP-200/300 inserted into any socket with a base address of
300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the Client Driver will
proceed to the second command line argument and attempt to configure the card with
a base address assigned by Card and Socket Services and IRQ 10. If IRQ 10 is also
unavailable, the Client Driver will proceed to the third command line argument and
attempt to configure the DSP-200/300 with a base address and an IRQ assigned by
Card and Socket Services. If the Client Driver can successfully configure the
DSP-200/300, the RS-422/485 output drivers for will always be enabled, and RTS-CTS
modem control handshaking will be disabled.
2.1.2.6 Example 6
DEVICE = C:\DSP-200\DSP230CL.SYS (b300,i5) ( ) (i10)
In example 6, the three command line arguments of example 5 have been rearranged.
The Client Driver will first attempt to configure a DSP-200/300 inserted into any socket
with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the
Client Driver will proceed to the second command line argument and attempt to
configure the card with a base address and IRQ assigned by Card and Socket Services.
Since the second command line argument includes all available address and IRQ
resources, the third command line argument will never be reached by the Client Driver.
It is the user's responsibility to place the command line arguments in a logical order.
