Re: How to Change Baud Rate for COM Port?

I am trying to use software to download information from an external device and I'm getting an error message. The help file suggests it could be that the COM port baud rate is not set correctly. How do I do this on Windows XP?

The baud rate it set in whichever application you are using to access the port. What is the client software on the PC?

Go to the Device manager, find the com port you want to change, click on it to open the properties page, click on the port settings tab and there you are. All the settings are available to you. bps; data bits; parity; stop bits; flow control and advanced where you will find the buffer settings. Good luck

The software on the PC is G7ToWin, an application used to transfer information to/from GPS receivers.

Neat - You'll nee dto set the baud rate from within the application itself - im not familiar with that packge, so I can't tell you exactly. I do know that most NMEA compliant equipment will be using 9600 8N1

I installed the app to take a look. It appears that if you select GARMIN, then only port rate available is 9600. Other make/models have the option of different port rates.

Something to try, assuming your Garmin unit does indeed need 9600 8N1...

Open a cmd window: click on Start -> Run, typing in cmd and click OK.

Type in "Mode Com1: Baud=9600 Parity=N Data=8 Stop=1" [enter] (without the quotes). Close the cmd window and try the app.

RE: How to Change Baud Rate for COM Port?

Having a similar problem here.

The device connected to COM1 needs a baud rate of 57600.  The default baud rate of COM1 is 9600.  At the moment, every time I need to use the device I power on the computer and change the baud rate of COM1 to 57600 in Device Manager.

I tried to remedy this by typing the following in cmd:

"Mode Com1: Baud=9600 Parity=N Data=8 Stop=1"

However, after restarting the computer the baud goes back to 9600.  Any helpful hints?
