Jul 11 13:17:50 <aturley>  hey, i'm working with an Ericsson F5521gw using the mbm driver. i was having problems communicating with the modem until i modified the driver to  call g_at_tty_open with  options that set the baud, parity, stop bits, and data bits.
Jul 11 13:17:57 <aturley> has anyone else run into a situation like this?
Jul 11 13:18:04 <aturley> is there a reason these things aren't set in most calls to g_at_tty_open?
Jul 11 13:23:13 <denkenz> most usb devices are not true serial devices, so these options are ignored
Jul 11 13:27:18 <holtmann> aturley: Ericsson told me that these are needed.
Jul 11 13:28:00 <holtmann> +       options = g_hash_table_new(g_str_hash, g_str_equal);
Jul 11 13:28:02 <holtmann> +
Jul 11 13:28:02 <holtmann> +       if (options == NULL)
Jul 11 13:28:02 <holtmann> +               return -ENOMEM;
Jul 11 13:28:02 <holtmann> +
Jul 11 13:28:03 <holtmann> +       g_hash_table_insert(options, "Baud", "115200");
Jul 11 13:28:03 <holtmann> +       g_hash_table_insert(options, "Parity", "none");
Jul 11 13:28:05 <holtmann> +       g_hash_table_insert(options, "StopBits", "1");
Jul 11 13:28:06 <holtmann> +       g_hash_table_insert(options, "DataBits", "8");
Jul 11 13:28:10 <holtmann> +       g_hash_table_insert(options, "RtsCts", "on");
Jul 11 13:28:57 <holtmann> The also needed a double flush.
Jul 11 13:28:58 <holtmann>         tcflush(fd, TCIOFLUSH);
Jul 11 13:28:58 <holtmann>         tcsetattr(fd, TCSANOW, &ti);
Jul 11 13:28:58 <holtmann> +       tcflush(fd, TCIOFLUSH);
Jul 11 13:28:58 <holtmann> +       tcflush(fd, TCIOFLUSH);
Jul 11 13:29:15 <holtmann> Seems the F5521gw is rather picky about its serial lines.
Jul 11 13:30:54 <aturley> holtmann: thanks.
Jul 11 13:31:10 <holtmann> I have one of these modules at home. Just not tried it yet.
Jul 11 13:31:12 <aturley> i haven't had to use the double flush, but it probably woudln't hurt.
Jul 11 13:34:59 <aturley> would you expect these changes to cause problems with other devices that use the mbm driver?
Jul 11 13:37:00 <denkenz> These probably should be set specifically for the F5521
Jul 11 13:37:12 <denkenz> a udev env variable might be needed
Jul 11 15:54:22 <denkenz>     [ org.ofono.NetworkRegistration ]
Jul 11 15:54:23 <denkenz>         Status = denied
Jul 11 15:54:23 <denkenz>         Mode = auto
Jul 11 15:54:23 <denkenz>         Name = 
Jul 11 15:54:47 <denkenz> This is from my ZTE Vodafone stick
Jul 11 15:55:36 <denkenz> So it probes the atom fine
Jul 11 16:02:23 <holtmann> It might has a network lock.
Jul 11 16:03:20 <denkenz> I'm using an Australian SIM
Jul 11 16:03:28 <denkenz> But that is besides the point, CREG=? works on this device
Jul 11 16:09:31 <holtmann> Seems like these other ZTE dongles are broken heavily.
