  This driver supports Solaris 2.x on the Sun SPARC platform.

 Introduction.
   The Digi device driver software has been written to support Digi
   PCI asynchronous serial communications adapters for Solaris on
   the Sun SPARC platform.

   Support for up to seven Digi Acceleport Xr, C/X, EPC/X and Xem 
   PCI serial communications adapters. 

   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.

 Enhancements.
   -Added support for the 422 Xr adapters.
   -Fixed problems seen in last release with dpa and ditty functionality.
   -Fixed problems seen in last release with concentrators not downloading
    properly and going to "AC".

 Known Limitations.
   - PCI support is limited to Solaris version 2.5.1. and later.

 Manual Errata.
   -None.
