$ man skill:
$ man skill：
SYNOPSIS
skill [signal] [options] expression
PROCESS SELECTION OPTIONS
-t, --tty tty
The next expression is a terminal (tty or pty).
EXAMPLES
skill -KILL -t /dev/pts/*
Kill users on PTY devices.
So it should be something like(can't verify it) : skill -STOP --tty /dev/ttyUSB0
所以它应该是这样的（无法验证）： skill -STOP --tty /dev/ttyUSB0
