INTRODUCTION

  The Digi HP-UX Realport driver makes the ports on a Digi
  Ethernet-based Serial Product (such as a Digi PortServer)
  appear as though they are local HP-UX tty devices directly
  attached to the computer.


SUPPORTED PRODUCTS

  Digi One RealPort Device Server
  EtherLite 2
  EtherLite 80
  EtherLite 160
  EtherLite 162
  PortServer 8
  PortServer 16
  PortServer II 16
  PortServer TS 2
  PortServer TS 4
  PortServer TS 8
  PortServer TS 16


ENHANCEMENTS

  Arbitrary integer baud rates are now supported via an option in
  the "ditty" tool called "cspeed".

  The driver now fully supports use of the Digi EtherLite modules
  listed above with this driver, including the EtherLite 80, provided
  the EtherLite module has been loaded with RealPort compatible
  firmware.


BUG FIXES

  None.


KNOWN LIMITATIONS

  This device driver no longer supports HP-UX 10.10.

  Older versions of SD-UX (from 10.20) may complain about the data model
  revision of the package information, but install should still work.

  This driver does NOT support HP-UX 11i version 1.5 (Itanium).


HISTORY

  1.2.3

    Now installs on HPUX 11.11, also known as HPUX 11i.
 
    Now works with newer units listed above. Fastbaud rate set is now:
      0 - 0
      50 - 57600
      75 - 76800
      110 - 115200
      134 - 131657
      150 - 153600
      200 - 230400
      300 - 460800
      600 - 921600
      1200 - N/A
      1800 - N/A
      2400 - 2400
      4800 - 4800
      9600 - 9600
      19200 - 19200
      38400 - 38400

    Please note that if you select a baud rate that a unit
    does not support, the results are unspecified, and you will
    not get an error message.

  1.2.2

    Added support for new fastbaud rates.

  1.2.1

    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.


  1.2.0

    The device driver added 64-bit support under HP-UX 11.x.

    An enhanced multi-processor implementation was released in
    order to address intermittent deadlock issues.

  1.1.1  

    Fixed a problem with configuration of more than 10 Portservers.

    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,
    causing the modem to hang up.

  1.0.0

    Initial Release.
