1. The Status value in the bottom left of the UCM/GSM screen will show the current GSM signal strength 0 to 4. In previous firmware, the GSM signal strength is displayed only for 1 second after which is followed by Normal/No Error. The status \"Normal/No Error\" has been removed as it provides no information and prevents the GSM signal strength from being displayed.
   
2. The signal strength 0 to 4 is followed by text describing the level number, eg 0 - No Network, 1 - Weak, 2 - Fair, 3- Good, 4 - Strong. This is not done by firmware, it is in Comfigurair defaults. To update the defaults, go to file > Update Defaults in Comfigurator. This updates the defaults. Close and restart comfigurator to activate the new defaults

1. The reply to an SMS command to Control Key 5 gives the wrong text. It shows the text for control key 1 instead. However note that the sms operation works, only the reply is not correct
   

Bugs Fixed

1. Phone numbers with 7 digits will get the wrong reply when sending SMS to the UCM/GSM4. The UCM/GSM4 will always send the Help Text (1) and (4). This occurs if 7 digits appear in caller ID. Note that this may or may not include the country code, depending on the carrier.  This problem has been reported in South Africa and Cyprus. Please upgrade to GSM4 v 7.048

Bus Fixed

1. Fixed \'H\' shunt showing wrong signal strength on LEDs.
2. Fixed in event of communication failure/restore, UCM/GSM only dialedto first number twice but  Second number is not dialled.

Improvements

1. Improvement on Comfigurator Status reporting to  UCM
2. Implement prevention for storing more than 160 characters in create text message command.
3. Add new status to inform when send sms queue is full.
4. Implemented SMS operations in PDU  mode to support foreign language text messages. This is \"Non English\" check box. However the max text characters  for non-english mode is halved as 2 bytes are needed for each letter
5. Implemented multiple concatenated sms.

This supports UCM/GSM4 features

To upgrade firmware and UCM/GSM3 to UCM/GSM4 see the topic http://www.comfortforums.com/forum48/3527.html

If an 256K bits EEPROM is not inserted in the U2 socket, UCM/GSM4 will behave like UCM/GSM3 ie it will not send Help messages and status messages by SMS

Please take not of known bugs below

Known Bugs

1. When \'the H\' is shunted, the network strength is wrongly reported in Comfigurator and on-board LEDS shown are wrong.  However, if the UCM/GSM4 is de-selected and reselected again, the strength reported in Comfigurator is correct.
2. When UCM/GSM loses communication or communication restore, the second phone number in Security Mode tab is not dialled out. Instead, the first phone number is dialled twic
3. If no feedback type assignment in Control Item, the reply SMS has missing \"Control Group\" and \"Control Item\" field.

Note that non-english alphabet is not supported yet eg Chinese, Japanese, Arabic

Incoming SMS commands  in other languages may be accepted if the message has only (, numbers and ) characters
