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 EtherLite Family
  Digi Flex Family
  Digi One Family
  Digi CM Family
  Digi PortServer Family
  Digi PortServer II Family
  Digi PortServer TS Family
  Digi PortServer TS MEI Family

  Digi PortServer TS H MEI Family
  Digi PortServer TS P MEI Family


ENHANCEMENTS

  Added support for HP-UX 11i v2 (11.23) for PA-RISC and Itanium.


BUG FIXES

  None


KNOWN LIMITATIONS

  Encrypted RealPort

  The HP-UX software requires an external random number generator on the system.
  If you want to use the encrypted layer in the driver you must install a Random
  Number Generator.
  The following points should be noted:

    o HP-UX 10.20 is not supported with Encrypted RealPort.

    o HP-UX 11iv2 has SRNG (Strong Random Number Generator) already built in.

    o HP-UX 11i requires SRNG (Strong Random Number Generator) to be downloaded
      from the HP website:  "HP-UX Strong Random Number Generator" located at:
      http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=KRNG11I

    o HP-UX 11.0 PRNG can be downloaded from:
      http://freshmeat.net/projects/hpux11-random/

  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 the install should still work.


HISTORY

  1.3.5

    Added support for Realport with encryption.

    Added support for up to 2046 RealPort products.

    drpadmin now allows "stacking" multiple RealPort Products off
    of one tty id.  For tty ids that are 1 character, there can be
    up to 999 ports stacked on that id.  For ids that are 2 characters
    long, there can be up to 99 ports stacked on that id.

    Fixed panic under SMP kernels.
    Could be caused by a port close, followed by a rapid port open.

    Fixed "Protocol decode error" problem.

    Fixed "stop" problem in the drp.daemon script.


  1.3.2

    The driver now provides an option to allow a FLUSH not to block, even
    when the RealPort-enabled Product is not reachable on the network.


  1.3.1

    Changed default port settings after an open. The ports will
    now behave just like HP's native serial ports on open.

    Added dinc, dgelreset, and dgipserv to the driver package.  Please
    check their respective man pages for further information.

    Fixed kernel panic when using driver on HPUX 11.0 64bit.

    Fixed possible NULL byte problem when doing a read right after an open.

    Fix an "assert" message that would occur when the realport daemon
    was killed.


  1.3.0

    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.

  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.
