modem Does not work with multiple port gsm gateway

I can identify, send and read sms with gammu.
But using this module, getMessages and sms callback is seemed to be never called.

Please take a look at https://github.com/emilsedgh/modem/issues/12 I think you just should use a different port.

Thanks for your quick response :)

There are 4 COM ports for 4 modems (with 4 seperated SIM cards). I can use gammu (and sms module, a gammu wrapper) on each of every port to send and receive sms. But I cannot even send sms when using your module.

I switched from using sms module to your module and totally love it. The API is straight forward, no need for external software installation and config file. I used it fine on my other GSM modem. But on this bulk sms device, the module doesn't seem to work.

Well unfortunately I have never used such a device and do not have access to one. I'm interested to help you with this, though.

There's one way we could do it. If you attach your device to a box and give me (limited) SSH access maybe I can find out how this device works?

If that's ok with you, please note that I will also need the program minicom to test it.

Thanks.
