UART
uart.baud
Abbreviation
ua b
Access
get/set
Description
Sets the UART baud rate. If raw
argument is NOT used, baud rate
must be one of the following standard rates:
300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600.
Some UART baud settings may be excluded by the hardware platform. See the topic UART Ranges
for your platform in the platform hardware documentation.
If the optional raw
parameter is supplied, then the rate may be any value.
After changing uart.baud
, save and reboot to effect the change.
