1. How to choose GSM Device for
Kylix SMS ActiveX Control?
-
We recommend using GSM Modem, which is
better in performance, stableness, and compatibility compared
with mobile phone, and it's able to work continuously without
charging, its signal quality also outperforms mobile phone.
Commonly used GSM Modem includes WAVECOM, SIEMENS, ERICSSON,
MOTOROLA etc, we recommend using WAVECOM WMOD2.
-
Mobile phone is also a good choice for the
software that doesn't have a large number of messages to be
sent. With so many brands of mobile phones exist in market, an
outdated model are preferred. Because they are cheap, and the
stability have been tested by the market. Features such as chord
ring, color picture and camera contribute nothing to the system,
on the contrary, it decreases the standby time and increases the
charging times. Among commonly used brands of mobile phones on
the market, Nokia and Siemens are most suitable to this work,
and most importantly, Siemens shows best support and
compatibility for AT command set of GSM device standard, we
strongly recommend using these brands.

3.
How to Set Connection Mode?
-
Kylix SMS ActiveX Control supports GSM
device with different interfaces, including serial port, USB,
Bluetooth, Infrared. For USB interface, usually it is simulated
to a virtual serial port by installing the device driver. And
then you can choose the virtual serial port. If you are using
GSM device with Bluetooth interface, be sure to install a
Bluetooth adapter onto your PC, the adapter driver will then
simulate Bluetooth interface to a virtual serial port. And then
you can choose the virtual serial port. For GSM device using IR
connection, there are 2 communication modes. One is connecting
through IR protocol by choosing Infrared. The other is
simulating IR to a virtual serial port, and you should choose
virtual serial port, rather than Infrared.
4. Unable to
connect to the device.
-
Make sure that the SIM card is valid and well inserted
into the socket, and check if the SIM card is set pin code. If the SIM card
is locked, unlock it first.
-
Make sure that the property values of ConnectionMode,
ConnectionProtocol and ConnectionParameter are properly set. Note that when
it is connected through an infrared virtual serial port under Windows98 and
Windows ME, the property value of ConnectionMode should be Serial Port Mode.
-
If the control does not support your GSM device, please
contact us for more information.
5. Message delivery
failures.
-
Make sure that your SIM card provide SMS service, and your
imprest is enough to send a SMS message.
-
Use the GetSMSCNumber method to check the SMSC number to be
correctly configured. If not, you can use the SetSMSCNumber
method to set a valid SMSC number. However, NOKIA phones may
have troubles to get and set a SMSC Number. Please check the
number manually through your phone.
-
The message delivery failure is sometimes due to a busy network.
You may set the property value of SMSSendTryTimes to "2"
or "3", automatically retry specified times after a message
delivery failure.
-
The control uses the PDU mode to send messages. If your hardware
does not support this mode, please contact us.
6.
Messages cannot be received by recipients.
-
"Successfully sending messages" only means that messages are
submitted to the GSM network, and it takes certain period for
the network to forward them to the receiving mobile phone. It
will take longer during a network busy time.
-
Check the property value of SMSSendValidity. If you set it to a
small value, then when the receiver mobile phone is temporally
not connected to the network or simply powered off, the SMS
center will discard the time-out messages, so that the
receiver's mobile phone is not able to receive messages.
Generally 1440 minutes (more than one day) is recommended for
this value.
-
You can send a message to yourself for testing purpose.
7. Unable to trigger
any events.
-
Make sure that the "visible" property is not set to "false". If
it is set to "false", the control cannot trigger any events, so
you need to change it to "true". To make this control invisible
when running, you can set the "top" property value to "-1000".
-
As for a dynamic instance, a parent window is required to
receive an event.
