1. INTRODUCTION
    The Digi device driver software has been written to support Digi
    PCI and ISA asynchronous serial communications adapters for
    Solaris on the x86 platform.

    This driver supports the following features:

        Cooked mode processing by the FEP/OS on the adapter.

        Support of standard data rates through 115K baud on hardware that
        supports it, and support through 921K baud on the Acceleport Xr 920.

        Support for RTS, CTS, DTR and DCD hardware flow control through
        stty and ditty, and also DSR hardware flow control through ditty.

        Support through ditty (altpin) for alternate pinouts on RJ-45 type
        modular connectors. DCD and DSR are swapped so DCD can be accessed
        with an eight-wire cable.
