REVISION HISTORY:
-----------------

Firmware Version V1.19: (Dated Mar 20, 2008)
--------------------------------------------

Bug Fixes:
----------
- Fixed wizard setup so it allows none alpha numeric characters for username and password.
- Fixed webadmin username and password so it allows none alpha numeric characters to be configured.

New Features and Changes:
-------------------------
- Support TCP connection keep alive.   When initiating a TCP connection for keep alive, the timeout is fixed at 90 seconds, if the TCP connection does not reply back in 90 seconds, it will consider TCP connect failure and it will drop and restart the PPP link.
- Added a new option in the webadmin UI to disable telnet access.   the new option is available in IP Setup --> General Configuration.
- Added APN setup option in the PPP setup screen for GSM modem only.
- Allow external application to query modem information based on AT commands that are configured.   Application can access URL http://192.168.2.1/modeminfor.html to get the IP address that is currently assigned to the wireless modem after PPP connection is established and it also show the results of all the AT commands that are configured.   The AT commands setup is in the webadmin PPP --> Modem Commands setup page.  The AT commands configured will be sent everytime it initiates a PPP connection to the network.   Here are some AT commands that can be useful for management purposes, refer to AT command guide for more details:

AT+CGSN
AT+CGMR
AT+CNUM
AT+COPS?
AT+CREG?
AT+CSQ

You can also retrieve the modem information without using a browser:
- make a TCP connection to port 80 (same as the webadmin port) and send data as:

GET /atinfor.html HTTP/1.1

--------------------------------------------

Bug Fixes:
----------
- Fixed ATM machine DHCP client not able to get ip address from DHCP server.   Fixed DHCP Server so it send NAK to “255.255.255.255”. Then, the client sends DISCOVER packet and server sends OFFER to unicast IP and client acquires IP from the server.

--------------------------------------------

Bug Fixes:

- Fixed the default packet filter rule problem.  When the default packet filter rule “LAN Any Any ACCEPT” is deleted and the “save-oem-defaults” command is issued and NAT Router is rebooted. the default filter rule still present in the webadmin.
- Fixed DNS update issue when PPP link is obtaining different DNS address after it connects.   DNS address should always show the latest address that is obtains by the current PPP connection.   This will allow the DHCP client to obtain the latest DNS settings in order to resolve hostname.


New Features and Changes:
-------------------------
- Added Autodialout hardware reset modem so whenever this feature is enabled, for every autodialout session that terminates, the internal modem is hardware reset.  This feature must be enabled via command only, the command Added to support this feature is:
