Linux虚拟串口

将下列Python代码保存成VitrualCom.py:

Code#! /usr/bin/env python

#coding=utf-8

import pty

import os

import select

def mkpty():

    # 打开伪终端

    master1, slave = pty.openpty()

    slaveName1 = os.ttyname(slave)

    master2, slave = pty.openpty()

    slaveName2 = os.ttyname(slave)

    print '\nslave device names: ', slaveName1, slaveName2

    return master1, master2

if __name__ == "__main__":

    master1, master2 = mkpty()

    while True:

        rl, wl, el = select.select([master1,master2], [], [], 1)

        for master in rl:

            data = os.read(master, 128)

            print "read %d data." % len(data)

            if master==master1:

                os.write(master2, data)

            else:

                os.write(master1, data)

在终端下面输入：

sudo python VirtualCom.py

便会显示：

slave device names:  /dev/pts/1 /dev/pts/2

这样/dev/pts/1与/dev/pts/2串口便相连接在一起了。
