Restart after firmware upgrade 1.51.25

[Justin Howson]

We have been experiencing that some isms gateways needs to be restarted after the 1.51.25 firmware upgrade. If the gateways are not restarted we get the following error when trying to send SMS texts.

”20-05-2014 09:10:01 – (SendSubmittedSMS) ID = 15 – Status = – Error number = 25 The server committed a protocol violation. Section=ResponseStatusLine”

we are using MultiModem iSMS: SF100-G-EU, SF400-G-EU and SF800-G-EU

Hi Justin,
You may be seeing a bug we found in the firmware. This bug was also in the previous firmware. Sometimes the resources will get depleted over time if something is port scanning or multiple connections are made to the same port in the port range 5000-5007. This can be avoided by disabling “TCP Connection” for all modems in the Cellular Modem menu. Note this only disables a feature that allows direct access to the modems, the TCP API is not effected.

Please try disabling the “TCP Connection” option for each modem in the Cellular Modem menu, this can be found in the Network section. If using a SF100 please make sure to save, click on “Save & Restart” and then click on “Save to Flash memory” so the setting change will persist through a reboot.

If it continues to have problems, we recommend creating a case in the support portal (support.multitech.com) so we can better troubleshoot the problem.

Regards,
Bryon

Hi Bryon

Thank you very much 🙂
We have now disabled the “TCP Connection” and will see if this solves the issue.
If it does not we will create a case in the support portal as suggested.

kind regards
Justin
