1. INTRODUCTION

    The Digi device driver software has been written to support Digi
    PCI asynchronous serial communications adapters for Solaris on
    the Sun SPARC 32bit and 64bit platforms as well as the
    Intel/AMD 32bit/64bit platforms.


    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.


2. SUPPORTED PRODUCTS

    Support of up to any seven of the following
    Digi Acceleport PCI serial communications adapters:

        Acceleport Xr and Xr 920 PCI.
        Acceleport Xem PCI.
        Acceleport C/X PCI.
        Acceleport EPC/X PCI.

    This driver supports Solaris 10 on the
    Sun SPARC 32bit/64bit platform and the 
    Intel/AMD 32bit/64bit platform.
