My bad, i looked better and see that you have made a discovery function. How many modems are you using? How many calls simultaneous? It's working fine? no calls stuck after you unplug/plug modem? I have found errors in source (master). And have made a lot a tests, like: unplug a modem in a middle of call - try to make a call with a modem that no support voice - send a sms at the same time you made a call - receive a call from modem A and route to modem B There is more tests that i have made, and made changes to correct it. Anyway, since i use xml_curl to grab the attached modems, and some modems can be removed/dettached or just have failure of power supply i reload/dettached/remove in according with the system/user interaction. And, that find_ttyusb_devices, don't work in FreeBSD, witch is the SO that i use *i can't user another system, i have made a lot of modifications in kernel and have a complete custom system based on that called BrbOS, with kernel encryption, custom drivers and other things. I make the control of calls using event_socket, and make custom routes according with the time, cost, user, configuration, usage, portability, destination... I need the system working that way, receive events when a modem cannot make calls, and control the modem to reload/attach when i need. So, because of it i create a daemon that i can control and know when a modem changes. I have found, in freeBSD and debian, a commom problem Its like, when i start the system for the first time Lets consider this ModemA (MA) - (ttyU0, ttyU1, ttyU2, ttyU3) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13) MA was unplugged/have power supply problem ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13) MC was unplugged/have power supply problem ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - ModemD (MD) - (ttyU11, ttyU12, ttyU13) MC was plugged/redicovered ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13) MA was plugged/redicovered ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13) As you see, sometimes the modems don't get the tty sequence 1.2.3.4. They get the sequence of free tty ports And, it's just in this test, when i have modems with 4/3 ttys Sometimes, the modem just RESET, and the tty was not free yet, so the modem jump a number in sequence MD was unplugged/have power supply problem ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - MD was on, but ttyU12 still oppened by FreeSwitch (mod_gsmopen) ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU13, ttyU14) As you see, the discovery will not work sometimes, you need to change to get all ttyports not getting as (ttyFOUND + 1) and (ttyFOUND + 2) And, like i said before, if you wan't to made changes i'm able to help or to rewrite the module, just need someone to help If you wan't, send me a e-mail or just reply here 2015-12-08 9:09 GMT-03:00 Shabbir abbasi <shabbirabbasi92@gmail.com>:
Hi: i have made patch for auto reconnect if dongle disconnected and display status of dongle connected or disconnected https://freeswitch.org/jira/browse/FS-8626
i think after this patch you dont need a seprate daemon to run thank u

I think the problem was when you declare interface as dead, like line 674 of gsmopen_protocol.cpp
https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end...
alarm_event(tech_pvt, ALARM_FAILED_INTERFACE, "gsmopen_serial_monitor failed, declaring interface dead"); tech_pvt->active = 0; ->>>> tech_pvt->name[0] = '\0';
You make a \0 in interface name
So, when someone call remove_interface() in mod_gsmopen.cpp
https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end...
To grab the tech_pvt, the function check for strlen or compare GSMOPEN_INTERFACES[interface_id].name (line 322 and 329)
Then, we will not found interface (tech_pvt), because "name" is nothing
continuing, in line 336 it's check if there is a tech_pvt
if (!tech_pvt) { DEBUGA_GSMOPEN("interface '%s' does not exist\n", GSMOPEN_P_LOG, the_interface); goto end; }
This check will jump the Close in line 385, causing a deadlock opened fd. res = tech_pvt->serialPort_serial_control->Close();
So i comment every line when you set tech_pvt->name[0] = '\0';
It's correct? Since when interface failed, and it's declared as died, the serial isn't closed, just marked as died, and the tty still opened causing a deadlock, if no one close this.
your reasoning seems sound, is the system still running ok?
Have you changed anything else?
Can you send me (to my mail, as an attach) a git diff? Or open a jira attaching that diff?
Btw, yes, I'm interested in understanding better how your system works (daemon, attach-detach, and all).
Also, big thanks for taking the time to look into the source code!!!

I make a daemon, witch manage USB using kqueue and other things, so, every time i plug or unplug a modem, i make a event, like ARRIVE and LEAVE.
This daemon have a list of modems, correlate with ttys ids - U3G (U0.0, U0.1, U0.2) and UMODEM (U0 U1 U2)
So, when a modem ARRIVE, and it's "attached" (configured), i call a "gsm reload". When a modem LEAVE, i call a gsm remove interface_x.
Using mod_xml_curl, i have dynamic config.
I use events, like gsmopen_dump list, to manage and controll interfaces, like when user "detach" a modem.
If you want, send me a e-mail, i will give access to my system and you can see what i'm talking about.
Anyway, i found things like in function
int gsmopen_serial_write_AT_noack(private_t *tech_pvt, const char *data)
// You make LOKKA(tech_pvt->controldev_lock);
Then call gsmopen_serial_write_AT(tech_pvt, data), and inside gsmopen_serial_write_AT, when something is wrong, you make UNLOCKA(tech_pvt->controldev_lock); and return -1
But, you check if (gsmopen_serial_write_AT(tech_pvt, data) != (int) strlen(data)) {
Then, you make again UNLOCKA(tech_pvt->controldev_lock);
Why make two times UNLOCKA(tech_pvt->controldev_lock); ?
It's like LOKKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock);
Another is in int gsmopen_serial_read_AT(private_t *tech_pvt, int look_for_ack, int timeout_usec, int timeout_sec, const char *expected_string, int expect_crlf) You make a LOKKA(tech_pvt->controldev_lock);, but there is some returns (inside try catch), without UNLOCKA.
Sorry if i make some mistakes in my explanation, but i just want to undestand how this funcions works.
I disagree with "Shaabir" about this module is not useable. I just think this need some changes to work fine. I already test this module with 40 modems for 7 days, and it's work fine, until i grab a deadlock in USB.
Giovanni, if you have time to chat with me, i will be grateful.
