RE: GSM Modem
Title: Message First thing I would like to dissuade you from using the M20 terminal - from my experience it has many flaws and its behavior is undefined in some common situations. second thing - why not use Kannel to communicate with the modem ? if you don't want to use Kannel, you can just take the source of one of the AT modules (my recommendation will be AT2) as a reference implementation (porting it to Java should be hard). --Oded Arbelm-Wise Inc.[EMAIL PROTECTED] "My life needs a rewind/erase button."-- Calvin and Hobbes -Original Message-From: Saurabh Bhardwaj [mailto:[EMAIL PROTECTED]]Sent: Monday, March 11, 2002 1:33 PMTo: [EMAIL PROTECTED]Cc: [EMAIL PROTECTED]Subject: RE: GSM Modem HiLet me first thank all who provided me with their valuable insights (Andreas Fink, Oded Arbel, Jörg, Dave Wilson, Dw.).

RE: GSM Modem
In my company we use Wavecom modems (specificly WM02B model), and its working perfectly for our needs (very high loads for both sending and receiving). it does not have a builtin power supply, but use an external adapter, but in addition to the external power adapter it comes with a connector and wires that allow you to connect the modem directly to any 12v DC power output, so you could have (for example) a single power source with battery backup power your entire modem rack. -- Oded Arbel m-Wise Inc.

Re: GSM modem
Use current cvs and at2 It works. If you want to use with 1.03. you need to modify some rows of smsc_at.c (pdu encode) Andrea - Original Message - From: David Holland [EMAIL PROTECTED] To: Fernando Primo [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Wednesday, October 24, 2001 10:46 AM Subject: Re: GSM modem On Tue, Oct 23, 2001 at 06:51:33PM +0200, Fernando Primo wrote: I try to probe kannel 1.0.3 to send SMS mainly, but i don´t sure about the kind of GSM modem that i have to use.

Re: gsm-modem -AT+ CNMI / no confirmation back to SMSC?
Hi. This actually works, thank you ! (The sender now gets a 'message delivered' instead of 'problem with receiving device' message). They (kannel and the modem) sure do talk a lot, though. But, I'm curious: This workaround, is it generally needed because of a problem with falcom, or is it temporary because something else needs to be fixed ? I don't see a performance problem in polling a gsm_modem (it doesn't get messages that quick anyway), but I wish the kannel.log didn't grow when there is no traffic... Also, I'm still curious about the return codes...
Re: gsm-modem -AT+ CNMI / no confirmation back to SMSC?
Matt, I would like you to patch the at code and let at2 code from Andreas Fink. By the way maybe someone won't agree with this, but having an at3 is not so good. Anybody using at currently has any comments? Andrea
Re: gsm-modem -AT+ CNMI / no confirmation back to SMSC?
Why is it that bad to have at3 ? Current AT module is buggy but it works, AT2 is worse cause sometimes my Siemens M20T just stop receiving any messages under it. I think adding AT3 till we get the perfect one is a good idea. I am willing to test the new At module which saves messages into a sim card. Thanks.

Quite frankly, the current AT module is so buggy it is not even worth thinking about using. I believe that if people want an AT module which works in a similar way to the original but works, then they should switch to the AT2 module it was alot more reliable then the original AT module and that was weeks ago - by now it must be even better ! Tomorrow I am going to send out my latest patches which will alter the smsc_at.c and smsc_p.h files. -- Matt Common computer data descriptions bitlicknibble byte
