 Introduction.
   The Digi device driver software has been written to take advantage of 
   the functionality of FEP 5.x with the facilities provided by Solaris 
   x86.  This includes the following:

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

   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.
   -Support for the Xr 920 (2-port adapter).
   -Support for Xem EIA-422 modules.
   -Option to run driver in interrupt-mode or the standard polling-mode.
