     NOTE:  There are two install diskettes included with this driver.  One is
            for use with AIX 4.1.X and the other is for use with 4.2.X and 4.3.X

     1. Bug Fixes.
          -Fixed problem with tty/lp devices coming up in Defined state after a
           boot.  Currently, if a device does not complete the configuration it
           will try to configure it again (a max of three attempts before 
           giving up).
          -Fixed system crash, caused by a bad ptr getting through service 
           routine unchecked.  This would show up on daemon resets, specifically
            seen when the PortServer would lock up or "freeze".
          -Fixed problem with print spooler, where a print queue stuck in 
           DEV_WAIT would hang the whole PortServer, not just that printer port.
          -Fixed data loss problem, seen on output when the stream is full.
     2. Known Limitations.
          -This Driver requires AIX Version 4.1.3 or higher.
          -Power Management does NOT work with RealPort.  If running RealPort,
           AIX's Power Management must be unconfigured.  If not unconfigured,
           the RealPort driver will disable Power Management.
          -There exists a severe system conflict with Motorola's model 603
           Powerstack, until this is resolved the model 603 is NOT supported.
     3. Comments.
          -For Realport use, all used ports on the PortServer must be set to 
           dev=host, see the Installation Guide and User Manual for more info.
     4. Basic Installation.
          -smit 
             select (Custom Install) and then choose  
             "Install From All Available Software Packages".
          -Command line
             "installp -a all" 
     5. Print Spoolers.
          -There exists a problem with AIX 4.1.4.0's installation of the printer
           packages.  Look in /var/spool/lpd/pio/@local/smit 
	       to see if the files in this directory are missing or size 0.
           If so, remove all these files and reinstall the printer backend 
           (printers.rte) with a force install.
     6. Transparent Print Setup.
           Make the TTY device, making sure that the TERMINAL type is set and
           that it matches the term-type set on the terminal itself.  Then
           a node must be created in the /dev/ directory by executing 
           "mknod <name> c <major> <minor>",
           where <name> is the name chosen for the xprint device, <major> is the
           TTY's major number, and <minor> is the TTY's minor number + 32768.
           The major/minor numbers can be obtained by executing "ls -l" on the
           TTY device node, located in the /dev/ directory.  A print queue can
           then be attached to the Transparent Print device by adding a queue 
           to the file in the /dev directory and entering the name of the newly
           created node.  Refer to the RealPort Manual for more information on 
           Transparent Print devices.
