Hi Jesper,

Diafaan SMS Server also supports SMS Text Mode which might be easier to implement than the default SMS PDU Mode. You can set the GSM Modem Gateway in SMS Text Mode with the CompatibilityMode setting in the Advanced Properties.

SMS Text Mode does not support all the options available in SMS PDU Mode but for your application that probably does not matter very much.

Hi Henk

Thx.
Not using a real modem. Have build a modem simualator that integretes with both Tetra & GSM, and also support a wakeup call! We have some technicians that needs to respond to service requests 24/7 entered into a Service Desk
Seems like I a responding with the OK on the \r rather than on the CTRL-Z.
Will do a fix, and let you know.

Hi Jesper,

A normal response from the GSM modem when Diafaan SMS Server sends a message looks like this:
2011/03/05 21:17:32.638 > AT+CMGS=19\r
2011/03/05 21:17:32.890 < >
2011/03/05 21:17:33.142 > 07911326040000F031220B911366254863F50000A90573B2393C07→
2011/03/05 21:17:35.144 < +CMGS: 246
2011/03/05 21:17:35.396 < OK

Your GSM modem appears to send an unexpected OK message directly after the send request. What GSM modem model do you use?

If you send the complete communication log to dms@diafaan.com (including the modem initialization commands) I might be able to see which options are supported by the modem.

Hi
I have installed a 30 days trial, and have set it up to use MS exchange.
At that point everything looks fine!
My problem is, when I send a mail, or using the "Send Message" nothing happens?
I can se that the AT command sent to modem:
2011/04/07 21:35:45.745 > AT+CMGS=38\r
2011/04/07 21:35:45.745 < OK
I would have expected AT+CMGS=\r
SMS text

Hope someone have an idea how to help

Jesper
