- Until the bit rate is found, URCs generated after restart will be output at 57600 bps. This applies only to
user defined URCs, such as "+CREG", "CCWA", "^SCKS" etc. The URCs "^SYSSTART" and "^SYS-
START ALARM MODE" will not be indicated when Autobaud mode is enabled.
Note: To avoid any problems caused by undetermined bit rates in the direction from ME to TE we strongly
recommend to configure a fixed bit rate rather than Autobaud mode.
• Autobaud mode and Multiplex mode:
If Autobaud mode is active you cannot switch to Multiplex mode (see AT+CMUX).
