Figure 0. DOS Client Output Enable Options.

Hinstructs the client driver 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 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.

2.1.2.1 Example 1

DEVICE = C:\SSP-200\ SSP231CL.SYS

In example 1, no command line arguments are specified. The Client Driver will configure a SSP-200/300 inserted into any socket with a base address and IRQ assigned by Card and Socket Services. The SSP-200/300 RS-422/485 output drivers will always be enabled, and RTS-CTS modem control handshaking will be disabled.

2.1.2.2 Example 2

DEVICE = C:\SSP-200\SSP231CL.SYS (b290,i11)

In example 2, a single command line argument is provided. The Client Driver will attempt to configure a SSP-200/300 inserted into any socket with a base address of 290H and IRQ 11. If address 290H or IRQ 11 is unavailable, the SSP-200/300 will not be configured. If the Client Driver can successfully configure the SSP-200/300unit, the RS-422/485 output drivers will always be enabled, and RTS-CTS modem control handshaking will be disabled.
