  Solaris 2.4, 2.5, 2.6, and 2.7 on Intel processors.  
  Also for 2.7 (32 bit only) on SPARC.

 Introduction.
   These are the release notes for the PortServer software.  They contain
   corrections and additional information not in the manual.  Please read these
   notes before attempting to perform the installation procedure in the manual.
   A copy of this document will be in /opt/realport when the installation is
   complete in both ascii and pcl formats.

 Bug Fixes / Enhancements.
   - Added OS level support for Solaris Intel 2.7

 Comments.
   -To set a baud rate of 57.6K, use the ditty command to set the fastbaud flag
    and set the baud rate to 50.
   -The ditty command provides support for RTS, CTS, DTR, DSR and DCD hardware
    flow control.

 Known Limitations.
   -If a PortServer loses power it may be necessary to wait for up to 2 minutes
    before communication is re-established with that PortServer.  If a login is
    not seen on a terminal after that time it may be necessary to kill the
    getty associated with the port so init will respawn the process.
   -The ditty altpin command has no effect with this product.  If altpin is
    required, you must use the "set flow" menu in the PortServer.  See the 
    PortServer manual for more information on altpin.

 Pre-Installation.
   -Before the first use, you may have to setup the PortServer as:
        set port range=* dev=host
    If a 3-wire cable is being used, then setup the PortServer as: 
        set port range=* dev=prn
    See the PortServer manual for more details about "set port" and "dev=".
   -The default TCP port number for the PortServer from the factory is 771.  
    This is set up on the host at installation time in the file 
    /etc/rc2.d/S26realport.
    The port number specified on the PortServer unit must match the number
    specified on the host computer.  To change the port number on the PortServer
    unit enter:
        set config netcx=771
    or, on firmware revisions starting with 3.3.X
        set config realport=771
    *Note:  This does not normally need to be changed.

 Installation.
   -The installation procedure places the device nodes into /dev/dty and 
    /dev/dpr by default.  Normally the install procedure would create symlinks
    from these devices into /dev/term and /dev/cua for modem and non-modem ports
    repectively.  However, due to limitations of the Solaris OS, creating these
    links using the Digi convention of a letter (for the controller/server)
    followed by a 2 or 3 digit number (for the port), causes error messages to
    appear when the machine is booted.  The product performs normally, but these
    error messages will appear, 2 error messages for each port created. It is
    desirable to have these entries in /dev/term and /dev/cua since many System
    Administration tools assume this location.
    The symlink problem is caused by the program '/usr/sbin/ports', which 
    requires that entries consist of either a single lower case letter or a base
    10 number. An entry such as a100 is illegal (according to this program).
