Multitech Multimodem EDGE

[sabine]

Hi,

We use MultiModem EDGE (Wireless Modem MTCBA-E) from MultiTech Systems (it seems to have included a Siemens MC75 Chipset).

We are not able to send SMS with the default drivers included in Hostmon. If we for example use the siemens tc35 driver I receive around 3 or 4 sms with only pieces of the message in it..

We are able to send SMS from a HyperTerminal session.

To send SMS we use the following commands:

Code: Select all

AT+CMGS="TelNumber", 129

after this we have to wait for the > character
then you can enter the text
after the text you have to send Ctrl-z and Return for sending the message.

Details under:

Is it possible to somehow send SMS messages with hostmon using this modem?

We use MultiModem EDGE (Wireless Modem MTCBA-E) from MultiTech Systems (it seems to have included a Siemens MC75 Chipset).

Hm. We exactly know, that some of our customers successfully use MultiTech modem (MTCBA-G-F1-EU). I do not think, there is a great difference in AT commands between MTCBA-E and MTCBA-G modems.

We are not able to send SMS with the default drivers included in Hostmon. If we for example use the siemens tc35 driver I receive around 3 or 4 sms with only pieces of the message in it..

Actually, some GSM modems requires SMS service center number before the PDU encoded data. It may depend on the modem type and even on firmware number. Siemens support several models with different modem type. You may try Siemens M35 modem type and Siemens M1. Such types have different GSM emulation.
BTW. Are you trying to seng long message? Please note: If a message is longer than 160 characters, HostMonitor will split the message and send several SMS to the recipient. If this is not really necessary, we recommend using compact mail templates for "Send SMS (GSM)" action.

You may try to use "undocumented" option SMS_MaxMsgLength. "Undocumented" means that the option is not accessible thru GUI. If you want to change max length of SMS messages, you should add "SMS_MaxMsgLength=<size>" line into [Misc] section of hostmon.ini file (<size> is a number between 40 and 4096, e.g. SMS_MaxMsgLength=155). Option is available since version 6.74

Is it possible to somehow send SMS messages with hostmon using this modem?

I think, it is possible. You just should setup the settings properly. What exact errors do you see in "SMS log"? Could you send the [GSM] section from hostmon.ini file to support@ks-soft.net?

Could you try the following setings? These settings work fine with Multitech Modem (MTCBA-G series):

BaudRate: 19200
ModemType: Nokia6650
Mode: PDU

We tried the suggested settings but did not work, is it possible that theres a special initializing string that the modem has to receive or something like that? We tried the modem with an other monitoring software (without initializing string) and we had no problems with it.

I just have sent you the test program, that should help us to resolve the problem. Did you receive my letter?

I finally got it to work by setting back to manufacturer defaults and configuring the modem per Hyperterminal with AT commands, baud rate 19200, PDU Mode and TC35 template (PIN required and servicenummer in international format).

Thanks for support!
