1. INTRODUCTION

   The RealPort service provides Windows 2000 seamless access to serial ports
   on Digi PortServer or PortServer II products.

   The Digi PortServer Product family allows Windows 2000 users to attach
   serial devices (modems, terminals, and printers) to the Ethernet based
   terminal server.  Users can use Windows 2000 RAS, Citrix, dial-out modem
   pooling applications and terminal server applications such as Point-of-Sale
   (POS) with the flexibility of terminal server connected devices.

   The RealPort Service requires the TCP/IP driver to be installed and properly
   configured.


2. SUPPORTED PRODUCTS

3. BUG FIXES
     If the you loose the ethernet connection, the driver will no longer fill up
     the event log with unsuccessful reconnect tries.
   


4. KNOWN LIMITATIONS

   RealPort will allow you to set Baud Rates up to 460k, but not all Digi
   Terminal Server products support this Baud Rate.  In your documentation
   Look up the highest available Baud Rate for you product.

   Software flow control characters set to the null (0x00) character for the
   Xon and Xoff character is not supported by the driver.

   The IOCTL_SERIAL_XOFF_COUNTER is not supported by the driver.

   There are some know limitations with Serial Printing.  Some Serial printers connected
   to the RealPort driver via the Digi Terminal Server line may not work properly.


5. HISTORY

   Version 2.3.10 - November 13, 2000
     BUG FIXES
	The RealPort Service will attempt to reestablish its connection to a
   	PortServer when a loss of its TCP/IP connection is detected.  This action
   	will occur for any currently open serial ports without user or application
   	interaction.  Previously when the TCP/IP connection was lost, any open
   	serial ports would remain in an error state until they were closed and
   	reopened.  This fix makes those steps unnecessary.
