Waddress specifies the base address of the memory window required to configure the SSP-200/300. Set address = D0 for a memory window at segment D000, address = D8 for a memory window at segment D800, etc. Valid settings for address are C8, CC, D0, D4, D8, and DC. If this option is omitted, a memory window at segment D000 will be used.

Odriver specifies RS-422/485 output driver enable option for theSSP-200/300. The SSP-200/300’s port may be configured for either full duplex or half duplex operation with this option. If this option is omitted, the default setting is the RS-422/485 port is configured for full duplex operation with the RS-422/485 output drivers always enabled. In half duplex mode, the RS-422/485 transmitter may be enabled and disabled via the RTS (request to send) or DTR (data terminal ready) signals. Both RTS and DTR are controlled through the Modem Control Register of the 16750. See the Hardware Information section for more information.

Option	Output Driver
o0	Always Enabled
o1	DTR Controlled
o2	RTS Controlled
o3	Auto-toggle

Hinstructs the enabler 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 SSP-200/300’s RS-422/485 port and a peripheral device. When modem control handshaking is disabled, the RTS and CTS signals from the 16C750 UART are looped back to each other. If this option is omitted, the default setting is RTS-CTS modem control handshake disabled. See the Hardware Information section for more information .

Before removing a SSP-200/300 from its PCMCIA socket, the Enabler should be executed to free the system resources allocated when the card was installed. For this operation the Enabler provides on additional command line option:

Rinstructs the enabler to release the resources previously allocated to the SSP-200/300. When the 'R' option is used, any settings specified by the 'B', 'I', 'O', and 'H' options are ignored.
