Hello Mark and Hank,

Thank you for the response to Walter's question, I have added this information to the review of the ConiuGo LAN modem.

Hey Mark,

you saved my day. I had exactly the same problem like Walter.
Turning off telnet worked like expected.

Best regards!

Hey Walter,

try turning off the option "Telnet Com Port Ctrl." in the ConiuGo web panel. Otherwise the modem will always respond with Telnet commands and I don't know if Diafaan can handle them. Otherwise you can try installing Lantronix Com-port redirector and you can configure your modem like a normal serial modem. But don't forget to turn off the above mentioned option or you'll get telnet commands also over the emulated serial connection.

Best regrads,

Hello Walter,

If you can communicate with the modem using telnet, then Diafaan SMS Server should be able to communicate with the modem from the same computer as well. The baudrate in the connection parameters is not used with a TCP connection so this can't be the problem. Internally the ConiuGo modem uses a serial port connection with specific baudrate to communicate with the LAN module, but if that was the cause of the problem it would not be possible to set up a connection to the modem with telnet at all.

The output of the 'Test' button suggests that there is a problem with the connection because the response is garbled. With a serial port modem this would point to a mismatch in the baudrate but I have no clue why this happens using a TCP connection.

Can you try to connect to the modem using the PuTTY terminal program with a raw TCP connection instead of a telnet connection and let me know if that makes a difference?

Regards, Henk

I have looked in your requirements of the LAN Modems and found that ConiuGo GSM GPRS LAN Modem ist working well.
I have bought that modem at Conrad. I have installed (Setup IP Parameters the Modem). I can talk with Telent to the modem,
it is also booked in the Operators GSM Network. But During Installation in SMS Server i put in type TCP/IP
my IP adress and port 10001 and when i press test, the Network ist writen perfect but the GSM Modem part is not filled out and i get GSM Modem Test failed.
Output of the log file is only this: - Open port:
> AT&FE0

< ,j`
For me it seems that the modem is waiting for Speed 38400 as it is in the Manual of the modem on not on 115200 baud.
Please can you help me in that Topic. I am like to install the whole Thing to a customer at the end of this week.
