Quatech DSP-200/300 - Manual (Page 11)

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.
