Hi,

We're a UK company that specializes in IP phone systems and I'd like to commission work to be done to support a new device with SMSTools3, this can be paid either to you or as a donation to the project.

The device is a PORTech MV-372 which is essentially two Siemens TS35i modules (two SIM cards in total) housed in a black box with ethernet ports. You can connect to it via SIP to send/receive calls and also connect to it over telnet to send/receive SMS over a mobile network.

I realise the Siemens TS35/TS35i have good support in SMSTools3 already, but after connecting with telnet SMSTools3 has issues logging in to the device before it can access the TS35i module directly.

I have one of these devices ready and a dedicated server with SMSTools3 3.1.14 installed anyone would like a try at this.

Details on how the telnet connection works can be found on page 36 of the manual for this device below. This works when using telnet manually, just not through SMSTools3.
http://www.portech.com.tw/data/MV-370%20user%20manual.pdf

Other people on the forum have had similar issues, such as the final post of this thread. This is partly why I am seeking someone to literally look at the issue directly as the forum holds no answers and the question has already been asked.
http://smstools3.kekekasvi.com/topic.php?post=3851#post3851

Any input you may have would be most appreciated, we intend to put SMSTools3 in to our phone system distribution and then convert SMS to XMPP (Jabber) allowing our customers to send/receive SMS to their customers or employees using a standard Instant Messaging client.

Naturally we prefer using Ethernet enabled GSM modems as our phone systems are mostly hosted virtually so serial or USB is out of the question.

Please reply below if your interested.

I have no such a modem, but I took a look at smsd behaviour during telnet negotiation using netcat as a telnet server and I see that smsd continuously sends telnet_login if there is no enough delay between login and password prompt.

So the session looks like:
smsd> AT
telnet> login:
smsd> <telnet_login>
telnet> Password:
smsd> <telnet_login>
telnet> anything else
smsd> <telnet_login>

This patch seems to fix this, but probably break something else ;-)

Clearly there is still something off with what is send/received or the timings of the events when speaking to this device.

If anyone is interested in some paid work writing a fix for this I'm all ears - I can provide a server to work on that has access to one of these devices. It's probably something small really.

Steven

As per your log it looks like the device echoing data characters it receives. (The seaquake is a login, isn't it?) If so, it is strange that it has not negotiated this feature (if it has there would be something like "Telnet: Got WILL for 1 (0x01), answering DONT." in the log).

Nevertheless, smsd doesn't care about any telnet options, so I see the two options here:
1) Somehow force the device not to use telnet echoing (probably some settings via GUI)
2) Implement echoing support in smsd :-)

Not sure if I can help here, but who knows. At least I am interested in identifying the root cause of the issue, so drop me a gmail (the same login as on this forum) if you can provide access to the device.

For those who still interested in using smsd with PORTech modems here is a patch that adds a new functionality required for that.

It introduces a number of new smsd.conf options, namely:
* telnet_crlf
* telnet_cmd
* telnet_cmd_prompt

Their meaning is quite straightforward. Here is a config that is known to work with at least PORTech MV-372:



Note, the init = ATV1. It is required to switch the device into verbose result code format mode, so it answers OK and ERROR instead of 0 and 4. It is required as smsd doesn't understand numeric codes. As an option you can store settings in the user profile via telnet like

ATV1
AT&W

and the use init = ATZ to restore these settings.

Hi,

I've applied the full patch that you included below this, and I'm still getting this same behaviour (smsd is continually re-sending the username....)

Any assistance or hints that you can offer would be greatly appreciated.

Hi Adam,

Wondered if you still have problems, I have setup a SC-495 which (as far as I can read) is similar to the portech 574. I also applied the patch, and it's working fine.

I had one small problem that required a change in the source code, we are setting up a 'send-only' SMS server, and after a while the command interface times out, and it needs an extra 'moduleX' command to get into command mode again.

I have not included a patch, since it needs cleanup .. and we are not done implementing yet

Hi

Do you think you could let me have your source code modifications pleae? I've bene trying to get this to work with a Portech MV-374 and with the patch applied I can send the first SMS but nothing after that. I get this error in the log:

2012-10-18 16:55:00,7, GSM1: -> 0011000C914457xxxx99150000FF0C6190392D9FD341F4F29C0E^Z 2012-10-18 16:55:00,7, GSM1: Command is sent, waiting for the answer 2012-10-18 16:55:05,7, GSM1: <- +CMGS: 33 OK 2012-10-18 16:55:05,5, GSM1: SMS sent, Message_id: 33, To: 4475xxxx9951, sending time 48 sec.

So looks like it's not handling the timeout of Module1 correctly, or something. My smsd.conf looks like this:

devices = GSM1 logfile = /var/log/smsd.log loglevel = 7 outgoing = /var/spool/sms/outgoing checked = /var/spool/sms/checked failed = /var/spool/sms/failed report = /var/spool/sms/report sent = /var/spool/sms/sent logfile = /var/log/smsd.log loglevel = 7 [GSM1] device = @192.168.xx.xx:8023 telnet_crlf = yes telnet_login = voip telnet_password = 1234 telnet_login_prompt = username: telnet_password_prompt = password: telnet_cmd_prompt = logout, module, module1, module2, state1, state2 telnet_cmd = module1 init = ATV1

Any help in getting this working would be greatly appreciated otherwise I'm going to have to buy another modem for my alerting.

Thanks

Hi slink,

This was the exact same problem we had, I'll clean up the code some time during the weekend and produce a diff file (if I can figure out how), and then post it here


Regards
Peter

that would be brilliant if you could, thanks!

These are the changes I made, and they where made to the source including the patch from this forum - I believe that is where you are right now

I added a cfg option called portech_module_name, if the portech sits a long time without any activity, the telnet 'session' times out, and it has to receive the modulename you want to contact, before you can send it any more AT commands.

This is a copy of my cfg for one of the devices

The telnet_cmd_prompt I is from my testing but didn't work, so it can be skipped, but somehow it survived - so I left it there. The most important is the 'nedds_wakeup_at' and 'portech_module_name'

I have not succeded in using 2 sims per module, so we only have 2 sims - one per module. Maybe if the need arises for us, I'll look into it ..

Good luck

Sorry to dig up an old thread but I am having issues applying the second patch to the source code (trying to get an MV-372 working, sends first SMS but timeout after).

The output I get is:

Any help would be appreciated

Never mind, got it working

Excuse me, i'm new on linux, what i have to do to apply the patch?

So it's 8 years later than when I started this post Now working somewhere else entirely.

Currently using version '3.1.21-3' from Debian 10 (currently in testing, but seems to have the latest patches included) but installed on Debian 9 using the below config...

[GSM1] device = @10.20.0.72:23 incoming = no telnet_login_prompt = username: telnet_login = voip telnet_password_prompt = password: telnet_password = 1234 telnet_cmd_prompt = module telnet_cmd = module1 init = ATV1 needs_wakeup_at=yes hangup_incoming_call = yes rtscts=no

Few things I've learnt so far which may be helpful to others...
- Using 'telnet_cmd_prompt' this way deals both with the initial request and any subsequent requests after the module times out
- This works fine with a MV-372 with part number 2N149A (on firmware v10.160) but didn't work with a MV-370 I had with part number 2K123C (which has no newer firmware than v6.694.j) - something about it asking for the module/timeout is different (despite a 370 only having one module).

So my current setup with the config above works great with my MV-372/2N149A/v10.160 device (I have a few if people are interested)...

Except if SMSTools3 starts up *before* the GSM gateway has.

Does anyone know of some setting I can use which means SMSTools3 will regularly try to re-telnet every so often? Because if there is a network outage (between the VM running SMSTools3 and the MV-372) or a power outage of the MV-372 - it means restarting the smstools service everytime at the moment.
