Unable To Open Com Port Win Error Code 2
XP SP2 workstations that are utilized in the plant. I use Clonezilla to reimage the workstations (yes, we have valid licenses for all units) when we have https://support.microsoft.com/en-us/kb/105940 to replace a hard drive or have warranty work that requires a new install. We have devices set up on specified comm ports. The printer is attached to COM1. When I test the unit to make sure all devices work, the printer test will not open COM1. When I use Hyperterminal to test COM1, I get https://social.technet.microsoft.com/Forums/windows/en-US/8328ff51-1f1b-48a6-8b72-3130295790ec/unable-to-open-com1-please-check-your-port-settings?forum=itproxpsp the message "Unable to open COM1. Please check your port settings." I've checked the BIOS of a working station and compare it to the non-working station. All information matches correctly. When I check COM1 property resources, the problem station looks identical to the good station, and not conflicts. IRQ 04 is the current setting. To get the reimaged workstation to open COM1, I open COM1 properties, resource tab, un-check then re-check the "Use automatic settings" box without applying the un-check status. After re-checking the "Use automatic settings", I click OK. I then go back to see what the settings are. It has changed to IRQ 07. This change works until the workstation has been rebooted then these steps have to be applied again. Also, if I perform these same steps on a workstation, I get the same results with the IRQ change. I do not have the problem with any comm ports except COM1. We're using canned software. Changing to use a different co

Shaaban 614 To be able to help you it would really help to know your development environment (what OS are you working on, how are you connecting to the serial port, etc.). The message suggests that another process using the serial port, it serial port problem could be as simple as need to close and reopen your terminal emulator. –dlu Nov 26 '15 at 20:01 Im using windows 8.1, and im connecting to the serial port via usb. –M. Shaaban Nov 26 '15 at 20:04 How are you connecting to the serial port (what software are you using to received the serial data)? I don't do much with Windows, but I think the problem that you're having is that your terminal emulator is expecting to see the data on your COM1 port but you're actually transmitting the data over USB and a virtual serial port. The serial monitor in the Arduino IDE picks up the serial port from the setting in the menu Tools > Port (which is also used for your upload), but other programs will need it to be explicitly set. –dlu Nov 26 '15 at 20:09 the software is built in the arduino IDE. I edited the post the code is not uploading, only compiling. –M. Shaaban Nov 26 '15 at 20:18 COM1 is usually reserved for the built in serial port in the computer. Your USB serial port is more likely going to be COM3 or COM11, or even COM23 rather than COM1. Make absolutely sure you have the right COM port selected, and that you have installed the right serial drivers for your board. –Majenko Nov 26 '15 at 20:19 | show 3 more comments 3 Answers 3 active oldest votes up vote 2 down vote I've got an idea.

driver problem Topic last updated 08 Nov 2010, by bert van kokswijk. 17 replies Jim Harris # 25 Nov 2009 . Edited: 01 Dec 2009 I originally started developing with the LPC2368 beta unit on a Windows XP machine. All was working fine with the Windows serial port driver. When the new (current) driver was released, I started using that and it wored fine. I then added a Vista machine to my office. I then loaded the new drivers onto the Vista machine and all worked fine. Recently, I received my LPC1768 mbed. I tried it on my Vista machine, and had to re-install the Windows serial port driver but all is working well on it. Now, either board works fine on this machine. I then tried to run the LPC1768 on my XP machine, and again found I had to re-load the Windows Serial Port Driver. When I did, Windows reported that there was a problem and could not start the serial port driver. I tried re-installing it several times, both from the website as well as from a local drive copy. Finally, I went back to my LPC2368 mbed. Re-installed drivers, and everything works fine. Going back to the LPC1768, it fails. It always says the driver could not start. I have uninstalled, re-installed, etc., but to no avail. Again, everything works fine on my Vista machine, just not on my XP machine, and only with the LPC1768 board...the LPC2368 works fine. Any clues as to what might be the issue? Thanks. Jim Simon Ford # 25 Nov 2009 . Edited: 25 Nov 2009 Hi Jim, Jim Harris wrote: Recently, I received my LPC1768 mbed.

To clarify, this behaviour is expected. Windows registers each different mbed as a separate device, hence the need to install again.

When I did, Windows reported that there was a problem and could not start the serial port driver. I wonder if this is some hangover from the old driver getting picked up when you put in a new device. However, we tested this all very thoroughly, including re-installing and upgrading, so it feels like a strange interaction/history thing. I'll have a chat with Phil (our USB guru) tomorrow, and see what he recommends. But in the mean time you could look at the following: (Note
