How to upgrade firmware using Windows Hyperterminal
---------------------------------------------------

1) bring up Windows hyperterminal 
2) power on the module and type d right away within 5 seconds
3) start xmodem upload using the firmware bin file.  The upgrade will take few minutes to complete
4) after upgrade is complete, power off and on the module and check the firmware version


Firmware version 1.10, Dated February 27, 2007
----------------------------------------------

Bug fixes:
----------
- Secondary DNS Server feature is implemented. If the name is not resolved by the primary DNS server, the module will try to resolve through secondary DNS server. 
- By Default HTTP is disable. 
- WLAN Link and Activity LED will work. 
- Heartbeat LED will glow as it is for command AT#WLANCONNECT 
- All boot-up messages will come only in user configured baud rate. 
- Firmware Download through XModem will work for user configured baud rate and not through default baud rate as was done earlier. 
- On Power up, RI, DCD and DSR signals are OFF (high) by default. 
- Host device parameter list file is written by the default firmware for demonstration of host device capability feature. 
- DCD signal is used only by TCP connection and not by WLAN LINK. 
- The lock up problem for continuous send/receive e-mails using SMTP and POP3 is resolved. 
- The lock up problem for continuous FTP transfer is resolved. 
- AT#VALL shows values of all parameters that can be configured. 
- After module connected to AP, the module appears to lock up if the AP is switched OFF. The module tries to roam in background. This roam feature is needed in cases where AP sends DE-AUTH packet if the STA remains idle for particular time. Due to roam capability the STA gets re-associated with the AP. 
To exit from roam and to come to AT command mode, enter the escape sequence on the serial terminal. 
For the functionality to work, the escape sequence feature should be enabled.  i.e. AT#CONTERMINATE=1 

- ATS2 setting is saved after cycle power. 
- DE AUTH packets from AP is handled and the module re-associates with AP when DE AUTH is received. 
- For SMTP, FTP, POP3, if the user gives less size of data then already specified then module will abort the session after specified time out. 
- MAC HANG problem after giving WLANCONNECT command for 5-6 times is resolved. 

New AT commands added:
----------------------

	1: Enable all boot messasges. 
Enable/Disable boot up message. 

AT#TCPAUTOLISTEN=<Value>
