如何在vb.net中一次动态地打开多个端口 [英] how to open multiple ports dynamically at a time in vb.net

问题描述

大家好

我正在使用一个与com端口通信的项目.但是我一次只能看到一个端口.在这里，我需要从可用端口列表中选择两个或四个.无论数字是多少，但是所有选择的端口应一次打开并同时运行.

例如，我的组合框中有com1，com2，com4，com8，com9端口，我将在运行时选择com2，com4，com9.
三个应一次打开.三个应单独运行.它们应该自动显示数据.我必须能够与打开的端口进行通信.

请帮帮我.

非常紧急的

Hi all

I am using a project that communicates with the com ports.but i can see a single port at a time.here what i need is from a list of ports available i''ll choose two or four.what ever the number is,but all ports choosen should be opened at a time and should run simultaneously.

for example,i have com1,com2,com4,com8,com9 ports in my combo box,i''ll choose com2,com4,com9 at run time.
the three should be opened at a time.the three should run individually.automatically they should display data.and i must be able to communicate with the ports opened.
