From: Daniel Watford Date: 01 Aug 2001 09:49:33 +0100 Message-ID: Lines: 141 User-Agent: Gnus/5.0808 (Gnus v5.8.8) XEmacs/21.1 (Cuyahoga Valley) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Hi, What is the correct way to change the baud rate of com ports under cygwin. I'm running windows 2000 and have set the desired baud rate of com7 to 38400. Running "stty -F com7" speed reports that com7 is set to run at 9600 baud. I have tried the command "stty -F com7 ispeed 38400" but receive the error message "stty: com7: unable to perform all requested operations". Then checking the speed of the port will show that it is still set to 9600 baud. Am I going the correct way about this? The main objective here is to be able to enter the command "cat com7" and view the data on that port correctly. Thanks Dan.
