Linux 虚拟串口

Linux虚拟串口：简介与使用指南

bash
# 安装 socat
sudo apt-get install socat
# 创建虚拟串口
socat -d -d pty,raw,echo=0 pty,raw,echo=0

2023/11/20 11:30:42 socat[12345] N PTY is /dev/pts/1
2023/11/20 11:30:42 socat[12345] N PTY is /dev/pts/2
2023/11/20 11:30:42 socat[12345] N starting data transfer loop with FDs [5,5] and [7,7]

python
import serial
import time
# 打开虚拟串口
ser1 = serial.Serial('/dev/pts/1', baudrate=9600, timeout=1)
ser2 = serial.Serial('/dev/pts/2', baudrate=9600, timeout=1)
# 向虚拟串口1发送数据
ser1.write(b"Hello, Virtual Serial Port!")
# 从虚拟串口2接收数据
received_data = ser2.readline()
print("Received data:", received_data)
# 关闭串口
ser1.close()
ser2.close()
