Hello, We are using the Nowsms lite licensed version, which talks to a wavecom gsm modem. The setup works fine for sometime (We are able to send and receive sms). After a few hours though, we are neither able to send/receive sms. The log is pasted below: 02:04:44:531 [2] ModemTest: OK 02:09:46:062 [2] ModemTest: Standard 9600 bps Modem 02:09:46:312 [2] ModemTest: OK 02:14:48:187 [2] ModemTest: Standard 9600 bps Modem 02:14:48:437 [2] ModemTest: OK 02:18:08:109 [2] ReceiveModemCommand: Error - 3E4 - 02:18:08:109 [2] ReceiveModemCommand: CancelIo We are unable to access the port through hyperterminal as well (Even after stopping the nowsms service). Any inputs to solving this problem will be greatly appreciated. | |||

Hi, Is this a USB modem or a serial modem? I would suggest checking the manufacturer web site to see if there are any firmware updates available. It sounds like the modem firmware is locking up. Here are some ideas/suggestions (aside from getting another modem): Does restarting the PC correct the problem, or do you actually have to turn the modem off and back on again? If restarting the PC corrects the problem, there is a hidden setting that can tell NowSMS to reboot the PC if a modem becomes unresponsive. To enable this setting, you must manually edit SMSGW.INI, and under the [Modem - Standard 9600 bps Modem] section header, add: RebootOnModemError=Yes Aside from this, the only suggestion that I have is that maybe it would help to slow down how quickly NowSMS is trying to talk to the modem. To do this, edit SMSGW.INI, and under the [SMSGW] header, add: ModemMaxBytesPerSend=1 Another possibility is a bad modem cable (or port). You'd be surprised how many times these problems are cable related. Try plugging in to a different port, and definitely try a different cable. -- Des NowSMS Support | |||

P.S. - The location of the SMSGW.INI file varies depending on the version of Windows you are running. For Windows Server 2003/2008, Vista and 7, it is in ProgramData\NowSMS. For Windows XP, it is in the installation directory (normally Program Files\NowSMS or Program Files (x86)\NowSMS). -- Des NowSMS Support | |||

Thanks for the quick response Des. This is a USB modem. Rebooting the PC corrects the problem. If we have to go in for a different modem, which model/make would you suggest? Will try the settings you have suggested. Thank You! | |||

I've had good luck with Option ICON modems. But that said, I use the RebootOnModemError=Yes setting with them as a safeguard also. |
