2.1.2.3 Example 3
DEVICE = C:\SSP-200\SSP231CL.SYS(s0,b300,i5,o2)
In example 3, a single command line argument is provided. The Client Driver will
attempt to configure a SSP-200/300 inserted into socket 0 with a base address of 300H
and IRQ 5. If address 300H or IRQ 5 is unavailable, the SSP-200/300 will not be
configured. In addition, if aSSP-200/300 is inserted into any other socket, it will not be
configured. If the Client Driver can successfully configure the SSP-200/300, the
RS-422/485 output drivers will be enabled and disabled via the RTS signal, and
RTS-CTS modem control handshaking will be disabled.
2.1.2.4 Example 4
DEVICE = C:\SSP-200\SSP231CL.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 SSP-200/300
inserted into any socket with a base address of 300H and IRQ 5. If address 300H or IRQ
5 is unavailable, the SSP-200/300 will not be configured. If the Client Driver can
successfully configure the SSP-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:\SSP-200\SSP231CL.SYS (b300,i5) (i10) ( )
In example 5, three command line arguments are provided. The Client Driver will first
attempt to configure a SSP-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 SSP-200/300 with a base address and an IRQ assigned by Card
and Socket Services. If the Client Driver can successfully configure the SSP-200/300, the
RS-422/485 output drivers for will always be enabled, and RTS-CTS modem control
handshaking will be disabled.
