From the GMS point of view I live and work in the boondocks: Grand Forks, North Dakota. (OK, so there is a decent argument that the entire US is GSM boondocks.) Anyway, I'm trying to figure out a way of sending and receiving text messages using a tool like smstools and a CDMA modem. I've found the MultiTech CDMA modem (MTCBA-C-N3-NAM) but I can't seem to find any success stories to go along with it. I was wondering if anybody has had any luck with either this modem and smstools3 in particular, or with sending/receiving text messages with a CDMA modem.

(I gather you mean smstools.meinemullemaus.de) Does it support the AT command set ? But even if it did, I think that the first question in the FAQ says it all regarding requirements, but I may be wrong. Alternatively, have you considered a Nokia handset with Gnokii ? http://smstools.meinemullemaus.de/faq.html 1) What hardware do I need? You need a Computer with at least one serial port. It does not matter how fast the CPU is and how much memory you installed. An old 486DX processor with 32 MB memory is enough. You also need at least one GSM modem with SMS command set according to the european specifications GSM 07.05 (=ETSI TS 300 585) and GSM 03.38 (=ETSI TS 100 900). When a vendor writes "SMS command set" without giving the specification names, then the device typically supports a subset of this specification. In this case you can surely send 7bit text messages and you can probably receive them. But its not sure, if status reports, binary messages or unicode messages work.

Yes, it has the AT command set, and MultiTech also sells a GSM modem (MTCBA-G) that is supported by smstools3, but a fairly casual reading of the reference manuals for both show quite a bit of diversity in the command set between the CDMA and GSM modems.

I was thinking that a "modem" would be a little more robust and easier to deal with in the rack than a handset would be. If I'm given a choice, I think I'd stay away from a handset, but I may not have a choice. :)

Think about it: mobile handsets have built-in UPSes :)
And in my experience (many years back), a nokia handset would start draining its ups as soon as it got a full charge, requiring daily reseat of the supply cord. YMMV so test and retest. On 6/21/08, Phil Regnauld <regnauld@catpipe.net> wrote:

If that s/b the case try using a Power Timer ie: something like , http://www.simplyhydroponics.com/24hr_digital_timer.htm , And program it to turn off once a week for 2-3 minutes .

Douglas, I have a RHEL server that I connected MultiTech CDMA modem (MTCBA-C-U-N3) and running smstools3 with it. Some hackery was needed and it still does not work ideally. What I mean by that, i had to modify the source code of smstools3 to work around GSM SMS message format. In the end it works except one thing: I believe, because of the way smstools addresses memory where the message to be sent is stored, it never releases that memory back. So as a result, it always retains the last message in memory and when a new one needs to be send and if it's shorted then then previous one, I see the new message and leftovers of the previous one at the end. Let me know if you want some documents that I wrote up when I was messing with it. Andrey Gordon [andrey.gordon@gmail.com] On Fri, Jun 20, 2008 at 2:25 PM, Douglas K.

From what I found is that smstools will only work with GSM AT command set, so if you are 'locked' into CDMA you are screwed in regards of using smstools. I'm attaching the html page that I wrote up after I got the modem working in case the server dies. I have to mention that i was only interested in sending sms, so that's the only part I was messing with.

geesh, I made a lot typos there. Also, i should mention that i don't know C, so don't judge me to harsh on modding the source code Andrey Gordon [andrey.gordon@gmail.com] On Fri, Jun 20, 2008 at 11:11 PM, Andrey Gordon <andrey.gordon@gmail.com> wrote:

Just in case you were contemplating getting the USB one and using it with a Mac, be aware that the serial-over-usb drivers are early-alpha quality, and although they were supplied as a universal binary, once my boss pried the source code to the original driver out of TI it became clear to him that due to endian reasons they had no hope of working on a PPC mac. So much for the G5 XServe that has run Nagios cleanly for ages. Joe-Bob says "caveat emptor". -r "Douglas K. Rand" <rand@meridian-enviro.com> writes:
