      set the time and date. Using an SNTP server the time
      could be got automaticly.
    - Every baudrate is now manual setable depending on
      the UART Model of the NetCom. If the value couldn't
      set within 5% difference, an error will be generated
      and no connection will be admitted.
    - If an error occur while saving, the variable name and
      a specific error message will be displayed.

    - The configuration parameter could now be save to a
      file and later loaded back from it.
    - It is now possible to set the password over SNMP in

    - Additional fixes to avoid hanging connections.
    - Make sure that every data left in the buffers are
      send over the serial interface if the connection
      are finished.
    - If in TCP Client Triggered Mode, make sure to wait
      a second before give up if we get no responce from
      peer.
    - Fix bug which could cause longer receive timeouts
      in NetCom 111 and 113.
    - Fixed "Ping-Bug": the Ip-address of the Netcom changed
      to the destination Ping-address.
    - If parmameter of TCP Mode are changed while Udp Mode
      is activ, it won't interrupt the UDP Mode and the
      other way.


* RELEASE_1_4_4 2004/03/30:

Version like 1.4.2 but add support for NetCom 111M.


* RELEASE_1_4_2 2004/03/02:

Bugfixes:
    - Fixed bug which could cause the NetCom to crash while
      serial communication or initialization.
      This could only happen with a NetCom 111.


* RELEASE_1_4_0 2004/02/16:

Features:
    - The telnet menu will be closed now after 10 min.
      without typing somthing.
    - If using the serial console menu, it will be restarted
      if the DSR signal switches from off to on.
    - It is now possible to enable and configure the TCP
      keepalive option globaly for all connections.

Bugfixes:
    - If in Driver Mode and the Control connection gets
      lost, the Data connection will be resetet also, to
      be sure not to be left in a bad state.
    - If the DHCP lease finally expires, the NetCom will
      close all connections and restart.
    - Bug fixed which could have made problems with UDP
      Mode timouts on multiport NetCom's.
    - Driver Mode Keepalive tests are working now also,
      if the Driver trys to connect very often. It aslo
      works if of any reason only the Control port is
      open.
    - Fixed bug in Webfrontend which was saving the wrong
      values of the listboxes.
    - Fixed a bug if the NetCom try to reconnect after a
      lost connection.
    - Fixed a bug which could cause that there is more data
      sent then received. Was mostly happen, if some sort
      of flowcontrol was used.
    - Fixed bug with XON/XOFF in Null Modem Tunnel Mode.
      The NetCom had not stopped sending it had received a
      XOFF character.
    - In XON/XOFF Mode it sends now faster the XOFF
      character, therewith it can't lose incomming characters.


* RELEASE_1_3_2 2004/01/08:
ATTENTION: This is a special version, which is not released for public
customers.

Bugfixes:
    - Fixed problem, that data was lost while receiving
      UDP packages.


* RELEASE_1_3_1 2004/01/07:

ATTENTION: This is a special version, which is not released for public
customers.

Features:
    - UDP Mode is implemented now. It is possible to set a timout
      value after which the received bytes are send to the
      destination. The NetCom scans the incomming data for trigger
      characters, if they match the data will be send too.
    - The NetCom sends its "Server Name" as Hostname with the
      DHCP request.
    - If the DHCP Server send a hostname, the NetCom use it as
      "Server Name".
    - Make sysContact and sysLocation setable in Webfrontend and
      Telnet menue.
    - Netstat and Statistic is now also included in the Webfrontend.

Bugfixes:
    - Typo fix in configuration menu.


* RELEASE_1_2_0 2003/09/19:

Features:
    - Telnet: netstat implementation for tcp connections.
    - Web: help support for configuration options.
    - Multi Connection support: The max. number of connections
      allowed is now configureable over SNMP, telnet and Webfrontend.
    - Security: If a Raw Mode connection is established, it is no
      longer possible to connect to the control port. So the port
      will not be unmeant switched to Driver Mode.
    - Security: If in Driver Mode the NetCom now only accepts
      connection from the same ip-address on the two ports.
    - Security: If in Driver Mode the NetCom now close a Control
      port connection if nobody connects after 1 min. at the Data
      port.
    - Firmware is now compressed.

Bugfixes:
    - Change the timing accessing the external UART.
    - Fixed broken configurations after failed DHCP request.
    - Fixed crash, if a client disconnects before the NetCom has
      accepted the connection.
    - Changed DHCP retries from 5 to 4, to reduce the timeout from
      120 s to 60 s.
    - If in TCP Client Mode Triggered, the NetCom haven't sent the
      first byte received from the serial port. This bug was only
      in version 1.1.3.
    - If the ShortHoldTime expires, it will be ensured, that there
      is no data left in any buffers before the connction will be
      closed.
    - Don't allow wrong IP-address like 0.0.0.0 or one with 255 in
      or 127.x.x.x.
    - Keep Alive tests wasn't working in version 1.1.3.
    - In version 1.1.3 the NetCom accepted multiple connection
      although if a Driver had connected jet.
    - Fix data lost at the beginning of a connection in TCP Client
      Mode in version 1.1.3.
    - Fix bug if multiple clients are connected and using handshake.
    - Fix bug in the tcpip stack if a RST doesn't match the last
      ACK sequence nummber, but fit in the window.
    - It is now possible to change serial settings in the serial
      console without changing the actual used settings.
    - Firmware update with a multible images file works now over
      serial console.
    - Fix bug if the TCP port is changed while connected, it wasn't
      updated after disconnect.
    - Fix bug if Null Modem Tunnel Mode don't connect right the fist
      time after reboot.
    - In Null Modem Tunnel Mode the synconisation of modem control
      lines works now better.
    - In Telnet menu "Save parameter" is now under "Save&Exit".


* RELEASE_1_1_3 2003/07/16:

ATTENTION: This is a special version, which is not released for public
customers.

Features:
    - Multi Connection support: The NetCom allows now in TCP Raw Server
      mode multiple connections simultaneous.
      Every byte received on any connection will be sent out on the
      serial line. Every byte received on the serial line will be sent
      on each connections.

Bugfixes:
    - SNMP: The entry vsnciPrdType of the vscom MIB responses now with
      the right length of the string.


* RELEASE_1_0_3 2003/07/16:

Bugfixes:
    - Without a real physical connected Ethernet, the NetCom doesn't make
      a DHCP request. Since the with the factory settings DHCP is enabled,
      it takes a long time for booting, if there is no DHCP server in the
      net. Just disconnecting the NetCom from Ethernet let him start without
      waiting for a DHCP response.
    - If the NetCom is configured to use DHCP, but the request fails, it
      doesn't starts a DHCP request again after some minutes, because the
      NetCom would loose all connection for this time.
    - Fixed broken firmware update over SNMP.
    - Fixed loosing FLASH space if a firmware is smaller then the old one.
    - In TCP Raw Client mode with Permanent connection chosen the NetCom
      will try to reconnect the destination if the connection was lost.
    - The TCP Raw Client mode doesn't disconnect anymore after changing
      from Triggered to Permanent connection.
    - Break Signal sending and receiving works now with Driver Mode and
      Null Modem Tunnel.


* RELEASE_1_0_2 2003/06/10:

Features:
    - Transfer modes:
        Driver Mode
        Null Modem Tunnel
        TCP Raw Server
        TCP Raw Client
        TCP Advanced Settings
    - Driver automaticly finds NetCom devices in the network
    - Automatic mode switching between Driver and Raw mode.
      With TCP Advanced Settings it is possible to configure
      the NetCom for using it in multiple modes, so it
      decides automaticly which mode should be used.
    - Configuration over:
        Driver panels
        NetCom Manager
        Serial console
        Telnet
        Web browser
        SNMP v3
    - SNMP: special VScom MIB included
    - Domane Name System (DNS) support
    - Serial interface configurable with external switch
    - Firmware update possible over every capabilities of
      configuration
    - Special precautions for Firewall environments
