엔드포인트에서 시리얼이 왜곡되는 원인이 되는 termios 설정은 무엇입니까?

두 개의 끝점이 있습니다. 하나는 Linux용 Windows 하위 시스템(Ubuntu)이고 다른 하나는 소형 AR9331 라우터(OpenWRT를 실행하고 16550 칩이 있음)입니다. USB-직렬 연결을 통해 연결됩니다.

AR9331에서 WSL로 전송이 예상대로 작동합니다.

WSL 콘솔:

~/openwrt_master$ cat /dev/ttyS5

HELLOTOALL

HELLOTOALL

HELLOTOALL

AR9331 콘솔:

root@OpenWrt:~# echo "HELLOTOALL" > /dev/ttyATH0
root@OpenWrt:~# echo "HELLOTOALL" > /dev/ttyATH0
root@OpenWrt:~# echo "HELLOTOALL" > /dev/ttyATH0

WSL에서 AR9331로 전송이 예상대로 작동하지 않고 왜곡되거나 순서가 잘못된 것으로 나타납니다.

WSL 콘솔:

~/openwrt_master$ echo "ILIKECHICKEN" > /dev/ttyS5
~/openwrt_master$ echo "ILIKECHICKEN" > /dev/ttyS5
~/openwrt_master$ echo "ILIKECHICKEN" > /dev/ttyS5
~/openwrt_master$ echo "ILIKECHICKEN" > /dev/ttyS5
~/openwrt_master$ echo "ILIKECHICKEN" > /dev/ttyS5
