I.   OVERVIEW:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

   This README file pertains to the current release of the firmware flash
   file for the MarkNet N2601e internal network adapter.

   Package file:     N2601E.zip
   Flash file name:  6_22_49.pfh
   FLASH RELEASE     6.22.49
   Release date:     January 26, 2007

   NOTES: 

   1) The flash file extension, .pfh, is used by the various utilities
      to distinguish between the various flash file types.  The file
      extension must not be changed.
   2) Note that pinging the adapter with large frames (over 1472 bytes)
      is not supported in this (and previous) firmware revision(s).  There
      are no problems with doing a 'regular' ping command.

   
II.  KEY FEATURES AND BENEFITS OF THE RELEASE:::::::::::::::::::::::::::::

   1) Adjusted DST begin and end dates for AST, EST, CST, MST, PST, 
      Alaska, and Newfoundland time zones to comply with 2007 DST
      changes. 

   2) Fixed issue where SMTP ports and timeout settings were not saved
      over a power cycle.

   3) Fixed DST dates in multiple time zones.

   4) Corrected an issue with paper size selection in the Scan to PC
       applet for non-English.

   5) Some minor fax adjustments

   6) Some other minor bug fixes.

   Reminder: Fax from Driver does not work when the n2601e is in
   "Fax Server" mode.  Users should send jobs directly from their 
   PC to the fax server in these configurations.

   WARNING:
   After updating the n2601e adapter with this firmware, an adapter
   "hang" can occur if certain network settings are immediately changed.
   When updating n2601e adapters, the printer does not properly "finish"
   sending the firmware to the adapter (however, the adapter receives the
   complete firmware file).  Because of this, the printer is still in a
   waiting state.  If an adapter reset is performed at this time (by
   changing vital network settings, telling the adapter to reset, or
   otherwise), the system will hang.  To prevent this from happening, send
   a print job or copy job to the adapter / printer or power-cycle the
   printer before changing network settings.

III. LIMITATIONS AND COMPATIBILITY OF THE RELEASE:::::::::::::::::::::::::

   One of the following methods are required to update the MarkNet N2601e
   with this release of firmware flash:
   
   1) The flash file can be sent down to the adapter via TFTP with a 
      binary transfer.  In the following examples the flash file is
      located in the C:\inaflash\ directory.

      NT server example:
         C:\>tftp -i 157.184.29.84 PUT C:\inaflash\6_22_49.pfh /dev/flash
         Transfer successful: 648434 bytes in 13 seconds, 19910 bytes/s

         Server)" task from the All Tasks list or click "Actions" -> 
         "Firmware Download (Print Server)" from the menus.

V.  RELEASE HISTORY:::::::::::::::::::::::::::::::::::::::::::::::::::::::

   6.22.26  (EC2)
   --------------
   Released: April 30, 2004

   1) Fax - New option allows the MFP admin to select between the fax
            station name and station number for use as the station ID.

      In the past, the n2601e product has used the fax station name when
      communicating with remote fax machines.  This is a widely accepted
      practice, but, strictly speaking, the fax T.30 spec states that
      only the characters [0 - 9,(,),+,- and space]  should appear in the
      station ID.  A new switch has been added to the analog fax
      configuration of the MFP.  This new option allows the MFP admin to
      choose between the station name and station number for use as the
      fax station ID.

   2) Fax - Improved recovery from loss of sync in V.34 transmissions.
      
      Improved V.34 synchronization in noisy line conditions.

   3) Fax - Improved V.34 mode with ECM disabled.

   4) Fax - Improved the handling of short fax frames that are received
            in ECM mode.

   5) Fax - Restrict fax transmission protocol to V.27ter, V.29 and V.34
            for French-made fax machines to improve compatibility.

   6) Fax - Fax Receive Paper Type and the Fax Log Paper Type settings
            were not always being saved from the web page.

      In some cases, setting the Fax Receive Paper Type and the Fax Log
      Paper Type on the web page was not working properly.
      This has been fixed.

   7) MFP / LDSS - Fixed a problem where certain LDSS scripts could
                   cause the MFP to crash.

   8) MFP / LDSS - Fixed a problem where using an LDSS duplex profile
                   may cause other simplex email and fax shortcuts to
                   erroneously send duplex.

   9) MFP - There was a slight possibility that a very busy network could
            slow down copy jobs.  Changes have been made that will reduce
            the likeliness of this happening.

  10) MFP - Non-printing characters on the Copy Settings page for Italian
            and Swedish have been fixed. 

  11) MFP - Fixed the "Known Issue" from EC1 where a specific memory
            corruption issue could cause a MFP error.

      In EC1, there was a memory corruption issue that could occur when a
      very specific scan jobs was attempted.  In test, we had found that
      the combination of TEXT + B&W + PS + 150dpi + A4 paper could cause
      this issue when using Scan to Email.  Other combinations may have
      also existed. 

  12) Network - Fixed a crash that could occur when a host did not ACK
                job_complete packets.

  13) IPDS - Added port 5001.

  14) IPDS - Fixed a problem where IPDS print jobs that were terminated
             with a TCP/IP Reset would cause the printer to stay Busy.
