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.
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.
