Solution:
The first thought is the Linux with the serial communication tool minicom.
But Minicom's settings do not automatically send this feature.
But it doesn't matter, we can use the script to let minicom send the data automatically.
Steps:
At the command line,
-> minicom
-> Ctrl+a->o
-> Carriage return
-> Selected D-script Program
-> set to/bin/bash

-> Save as default settings DFL

->ctrl+a, Q quit minicom

Then there's the write-send script, as follows:

#!/bin/bash

Flag=1

while [$flag = 1]

Todo

Echo 123456

Sleep 1

Done

Exit 0

I'll take it as a test.sh.

Finally, execute the script:

-> minicom-s test.sh
