ACER Android Communications Port (COM11) Driver

Helping people with computers... one answer at a time.

Because of an interaction with Quicken 2000, your machine may not be able to enter standby.

Android Communication: Use of COM Port for Data Transfer Back in 2013, our development team created a dashboard for Android which could display electricity network data in a workshop. Their main problem was that the device that collected the data stood alone and had to be connected to an Android device via a serial port. Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port. To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports. Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port. To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports. This is a driver library for communication with Arduinos and other USB serial hardware on Android, using the Android USB Host Mode (OTG) available since Android 3.1 and working reliably since Android 4.2. No root access, ADK, or special kernel drivers are required; all drivers are implemented in Java.

Why is 'Communications Port ... preventing the machine from entering standby'?

•

The full message is typically 'The device driver for the CommunicationsPort COM1 device is preventing the machine from entering standby'.

•

Apparently there's an interaction with Quicken 2000. This article out on the Dell support forums has moredetails.

I have Quicken 2004, not Quicken 2000. Task list shown when I do cntrl+alt+del does not show QAgent.exe running. What do I try now?

I also currently run Quicken 2004, but have had earlier versions of Quicken and when I uninststalled, I did not fully uninstall all 'shared' software components.

When I learned how to disable the mrtrate.sys device driver, I was finally able to use the Windows standby feature again!

The steps for disabling mrtrate.sys can be found near the bottom of this page:

I have only Quicken 2006. I did not find any reference to Quicken 2000 although I have had earlier editions of Quicken in the past. I did not have this problem with Quicken 2004. This is the message however I do get when I want to go to standby

Thank you very much. It worked. I am using Quicken 2000. You know I even tried to look for which driver is associated with which COM port number under Device Manager....I always thought that it could be a hardware like a modem or infrared which gets assigned a COM port and maybe there is a conflict between two devices.

But I don't have Quicken on my machine, so what is causing this?

Acer Android Communications Port (com11) Driver Windows 7

i remember using quicken on this computer, but i thought i deleted it. and i can't find quicken in any of the files on my computer.

i installed a program called lightsource, which is a series of geometrical graphics/colours/designs.

then i noticed problems with this computer using windows xp home edition service pack three, version 2002.

any suggestions to fix this problem? i like the computer to go into standby when i'm not using it for 30 minutes or so.

thanks,

I had the same problem even after following the instructions for Quicken 2000. I do not use the download function of quicken so as a test I renamed the driver files that quicken uses. These files are called 'mrtRate' and found under the subdirectories system32 and system32/drivers. Bingo, fixed the problem.
