INTRODUCTION

  The Digi HP-UX Realport driver makes the ports on a Digi Portserver
  appear as though they are local HP-UX tty devices directly attached
  to the computer.


SUPPORTED PRODUCTS

  Portserver
  Portserver II


ENHANCEMENTS

  None.


BUG FIXES

  The device driver could crash if PortServer nodes were added
  and removed in a particular order.  This behavior has been
  corrected.

  With 64-bit kernels, it is now possible to assign a link
  speed with drpadmin.

  Under 64-bit kernels, the RTS and DTR signals no longer toggle
  at awkward moments as a result of the mishandling of a standard
  termios ioctl.  This defect affected modems particularly, as
  the act of running most startup "profiles" resulted in the
  execution of "stty", which could cause DTR to drop, which
  could cause modem hangups.

  The installation scripts have been modified to allow for
  installation on platforms which support both 32-bit and 64-bit
  kernel operation.

  The RealPort daemon has been modified to workaround a bug in
  some HP-UX 11.x C run-time libraries which caused the daemon
  to fail to run against PortServers configured with an IP
  address instead of an IP name.  You may now supply either an
  IP address or IP name as originally intended.


KNOWN LIMITATIONS

  None.

    Fixed a problem with a transparent print hang after significant
    output to the terminal device.

  1.1.0

    Add HP-UX 11.x support.

  1.0.3

    Fixed a problem where DTR dropped immediately after a modem connect,
