Hello Dan,
Thank you for your response. I have looked into ModemManager version 1.6.4 and this patch you are mentioning in your e-mail does not reflect the line number in src/mm-base-modem.c:
@@ -219,6 +219,12 @@ mm_base_modem_grab_port (MMBaseModem *self,
"timed-out",
G_CALLBACK (serial_port_timed_out_cb),
self);
+
+ /* For serial ports, optionally use a specific baudrate */
+ if (mm_kernel_device_has_property (kernel_device, "ID_MM_TTY_BAUDRATE"))
+ g_object_set (port,
+ MM_PORT_SERIAL_BAUD, mm_kernel_device_get_property_as_int (kernel_device, "ID_MM_TTY_BAUDRATE"),
+ NULL);
}
/* Net ports... */
else if (g_str_equal (subsys, "net")) {
I also have built ModemManager1.6.4 for ARM architecture and run on my development board. However I am getting the following error:
ModemManager[1631]: <debug> [1491431437.689341] [mm-plugin.c:804] mm_plugin_supports_port(): (Generic) [ttymxc2] probe required: 'at, qcdm'

Could you tell me which version of ModemManager I should use?

Aleksander committed a patch two weeks ago that allow configuring the baud rate from udev rules, see:
