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

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?
