Illegal Replacement Description
[ ( left bracket
] ) right bracket
{ ( left bracket
} ) right bracket
~ space space
^ space space
\ space space
/ space space
` ' Single quote

 

15/3/2012    Major release SMSC V2.2 (74)   

  1. Changed the modem response logic to fail the message immediately. No retries. This forces the switch to take back the message and send it to a backup network.

  2. Added the failed log string on initialisation to the FATAL load window so the user can see why the application fails on start-up.

  3. Click on the progress bar to reset the test sequence on the modem.

  4. Short Test timer now 10 seconds not 30. Long timer is still 5 minutes.

  5. Extensive logging changes again.

  6. Example port fail on start up below.

 

15/3/2012    Minor release SMSC V2.0 (72)   

  1. Added a AT watchdog counter. If AT fails 20 times in a row it will reset the modem timer and begin a modem reset sequence.

  2. If there is an error in sending a message the client will go immediately unavailable. This will make the Switch delete messages if any in the queue and send the messages to the back up network. The client will resume Ready after an AT watchdog.

  3. The AT watchdog to the modem occurs every 5 minutes. If it fails it will drop immediately to a 30 second cycle.

  4. The AT command waits 2 seconds for a response from the modem.

 

13/3/2012    Minor release SMSC V2.0 (71)   

  1. The CNMI sequence was missing a COMREADY flag. After a successful CNMI sequence the modem will advise the Switch it is available.

 

9/3/2012    Minor release SMSC V2.0 (70)   

  1. The reset sequence has now an additional 15 second delay after sending the reset command to the modem before the start of the initialisation sequence.

  2. Reset has been fixed for the Wavecom modem. After the 15 second wait period the modem is then sent a command to reconnect to the Telstra system. Previous versions did not issue a reset to the modem on a periodic basis.

 

8/3/2012    Minor release SMSC V2.0 (69)   

  1. The autoreset has been changed to accept 0 seconds or 120 to 172800. This is necessary as the autoreset can not be used in the current version of the Intermax. Setting the autoreset to 0 turns off the capability. It is up to the client to reset the modem on a regular basis.

 

22/2/2012    Minor release SMSC V2.0 (68)   

  1. The reset logic has been changed again to test if the queue is empty regardless of the network type.

  2. The reset command is now logged

  3. When reset is activated manually or from the reset timer it sends an UNAVAIL flag to the switch.

                                                         

6/2/2012    Minor release SMSC V2.0 (67)   

  1. The reset logic has been changed to test if the queue is empty. Reset will only occur once the queue is empty

 

20/1/2012    Minor release SMSC V2.0 (65)   

  1. The reset logic has been changed to accommodate Intermax with no power on response.

20/1/2012    Minor release SMSC V2.0 (64)   

  1. The ClientPointer logic was improved.

  2. Changed the display of the global modem status.

19/1/2012    Minor release SMSC V2.0 (62)   

  1. The state was disabled in version (61). Now re-enabled for normal operation.

18/1/2012    Major release SMSC V2.0 (61)   

  1. The Client has two small text boxes on the top right which indicate the position of the input and output pointers in the queue. The left is the input pointer and the current queue size is 101.

  2. The textbox to the left of these is the information from the modem to the Client.

  3. The log information has been increased to show the the input string handling from the modem.

  4. The configuration to the modems has been changed as the Intermax requires additional strings to initialise the modem to SMS text mode.

  5. The Client will detect ERROR messages from the modem and try to reinitialise the modem.

  6. The Client availability is now linked to the watchdog. If the modem is in CheckSMSRx or SendSMS modes it will send to the Switch it is available when the watchdog activates.

  7. The comms routines have been greatly enhanced to cater for split packets in TCP mode as a result of the terminal server operation. The serial port has also been enhanced.

  8. Tested Intermax to 115200 baud.

  9. Added a reset external modem command in the Status tab

 

Latest SMS Server V1.30(58)        This is the latest exec.

V1.30(58)    Changed the input queue from 10 to 100 records.

The input queue was suffering from overload by broadcast SMS groups.

 

SMS Client V1.30 (Build 57).

The Client has been converted to Async comms to the Hub. This is hard coded.
