Script a COM port disable/enable reset

Hello,

Normal first post jargon:
I'm new, but like the forum, hopefully you can answer my questions, and thanks ahead of time to any that answer.

Problem: At work we use a program that likes to take hold of the local communications port, and doesn't like to share.

Current Solution:
In order then to use the COM port for another program/label printer etc. we have to first disable, and then enable the COM port.

What I'm looking for:
I have been trying to find a way to use a batch file to reset the COM port automatically without having to use devmgmt.msc every time I want to change programs.

Any help/advice would be appreciated. I just discovered KiXtart today and have liked what I've seen so far.

Thanks,

Andy

See if Devcon will do what you want.

Re: Script a COM port disable/enable reset

Hello ahoover and welcome to the board,

Another tool you could use is:
COMDisable

It will let you:
• View a list of available COM ports on your computer
• Disable and enable these COM ports

Operating System Requirements
COMDisable is supported on computers that are running the following operating systems:
• Windows Server 2003
• Microsoft Windows XP
• Microsoft Windows 2000 Service Pack 3 (SP3) or later

COMDisable Syntax
COMDisable uses the following syntax:

comdisable /list
comdisable /disable COMPortNumber
comdisable /enable COMPortNumber

Re: Script a COM port disable/enable reset

First, thanks to both of you.

Benny69, unfortunately that is a passive reset needed reboot. So that won't work for my scenario.

Allen, this worked for me. I'll add this to a batch script to run on startup, and add another on the desktop of the laptop to run on command.

Thnaks again, and hopefully at a later time I can jump into the logon KiXtart scripting world.

Hi Andy,
Could you please post the batch script that you uses? Can't make it work at all...

Hi Anders,

Andy made his last post in 2008 so I guess he is no longer an active user.

Can you share what you tried and the code you have up until now?
