The channels field tells you how many channels are on that port, not the channel number, and the first channel is channel 0 on each port. So there is no channel=1.
You have to use:
/system serial-terminal serial0 channel=0
/system serial-terminal serial1 channel=0
Or just drop the channel parameter completely (because there is only 1 channel for each port):
/system serial-terminal serial0
/system serial-terminal serial1
I can use the CLI command line to use channel=0,
But can not open the SMS receiver function, tip: couldn’t change SMS settings- timeout
CLI command line is unable to use channel=1,
Tip: no such channel failure:
SMS receiver function is also unable to use channel=1
/tool sms set receive-enabled=yes
