Page: 11 / 52

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 a
SSP-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.
