other. If this option is omitted, the default setting is RTS-CTS modem control handshake disabled. See the Hardware Information section for more information.

Uinstructs the Enabler to disable the QSP-200/300's interrupt status register and enable the Scratchpad registers of the individual UARTs. This option is only required in very rare cases where an application program requires access to the UART's Scratchpad register. If this option is omitted, the QSP-200/300's interrupt status register is enabled and the UARTs' Scratchpad registers are disabled.

Before removing a QSP-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 QSP-200/300. When the 'R' option is used, any settings specified by the 'B', 'I', 'U', and 'E' options are ignored. This option must be omitted when installing a QSP-200/300 into the system.
