GSM modems
Hello. I'm working on a project where we need to use GSM modems to be able to send and receive short messages; right now this is implemented through SMSTools. We are having a lot of problems like the modem hanging and stopping any communication with the computer, the modems suddenly saying the SIM card is bad or that the ISP network is refusing registration. Most of these are resolved by unplugging/replugging the modem. I was wondering: _ can (some of) these problems be FreeBSD related (e.g. USB driver issue, or something)? _ has anyone had any similar experience? _ can someone suggest a brand/model which works fine? (We tried three different ones, but all show some glitch). bye Thanks av. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Have you ever tried comms/gammu? We are having a lot of problems like the modem hanging and stopping any communication with the computer, the modems suddenly saying the SIM card is bad or that the ISP network is refusing registration. Most of these are resolved by unplugging/replugging the modem. Did you try to change a cable? Prior to using GSM modems we had tested some mobile phones and had got much trouble with their cables. I was wondering: _ can (some of) these problems be FreeBSD related (e.g. USB driver issue, or something)? So you use USB modems, aren't you? Which FreeBSD version have you tried? If it comes about USB, FreeBSD 8-CURRENT is very nice. It has a rewritten USB stack. And a release is approaching. _ has anyone had any similar experience? No. But we use comms/gammu and modems with COM interface. _ can someone suggest a brand/model which works fine? (We tried three different ones, but all show some glitch). Siemence MC35i is very stable.

what gsm modems?
Hi, I was wondering what GSM modems work with FreeBSD 5.1 at the moment? I'm setting up an intrusion detection system that I need to alert me by SMS should anything unusual happen. I'm planning on using comm/gsmlib but need to know what modems I can use (and if you have any recommendations or experiences, I'd love to hear about them).

(a perfectly standard serial interface) There is a standard GSM AT command set but each manufacturer might have their own quirks and special commands for battery life(!), etc etc. I mention battery life: your average cellphone should have a serial interface available and hence a console for AT commands. The components related to GSM comms are quite generic between cellphones and GSM modems and your results should be the same. Almost all available modems should be perfectly acceptable, you can also try a cell phone+serialdata cable. At my company we use siemens tc35 modems slaved to 8-port serial cards (comtrol octacable things) for SMS service testing. We haven't had any problems since we started using them three years ago.

Hi Niklas Tak a look at www.kannel.org That's an open source SMS and WAP gateay project.
