V25ter AT Commands
HL7618, HL7618RD, HL7648, HL7650, HL7688, HL7690 and HL7692
Notes
Not all listed rates may be available as they depend on the target.
The full range of data rate values may be reduced depending on hardware or other
criteria.
<baud_rate> is saved in non-volatile memory per AT port over module reboot when
AT&W is entered. It is not automatically saved after a +IPR write command.
After autobaud is activated on a UART port, the next AT command can be entered
at a different speed. +IPR is then set to the speed of this command. Autobaud is
then automatically deactivated.
When autobaud is activated on a USB COM port, any speed provided by the USB
driver is accepted. AT+IPR? responds with +IPR: 0 regardless of USB speed used.
