Connecting to COM1 doesn't work

I'm trying to connect to Cisco 877W through console port. All port parameters set up right. Result is

Hi MZN,

Thanks for reporting this problem. What operating system are you using on the machine where SecureCRT is installed?

Are you using a physical COM port or an adapter?

Can you successfully establish a connection to any other devices?

Hi MZN,

Here is some information that might help resolve the issue:
The SecureCRT error message saying "Error configuring port parameters for serial port COMx: incorrect function" occurs when another application is already using that port in a device driver context. Most commonly, there is a printer defined for that serial port that is in conflict.

In our experience, this problem is usually caused by an output device (like a label printer) connected to the COM port (printers have turned out to be the most commonly-seen culprits). If you have other devices that are attached to your computer, it's possible that one or more of these devices might be currently connected to the same COM port that SecureCRT has been configured to use, causing the error you're seeing. Some applications (such as Adobe PDF related software) also create virtual printer devices which can be associated with COM ports by default, leading to the problem you are seeing.

Note that the error message seen when a printer (driver) is connected to the COM port is different than the message you would see if some other serial application were already using the COM port. If the COM port is already in use by another terminal emulator, you would see "Unable to open
serial port COMx: Access is denied."

You can check current printer configurations for any conflicts by looking at the "Ports" tab of the Properties associated with each printer listed in the "Printers" section of the Windows control panel. If any printer is configured to use the same COM port that you are attempting to connect with in SecureCRT, you may want to try configuring SecureCRT to connect to a different port, or configure the printer to use a different port.
Does this help?

Hi rtb,

Thanks a lot! My problem was in Adobe PDF printer driver which used COM1. I deleted this device, and problem was gone. Thanks again!
