Stress test ttyS0 or other serial port

Tags: serial, linux, port, test
I would like an automated tool(s) that will stress test a serial port like ttyS0. I have a multiport (octal) serial board. I would like to test the driver for flow control, baud rate, etc. But I would like to make sure that it can operate under max load (serial driver loading and not kernel loading) and I would like to automate the tests.

I have already used minicom and set the baud rate to the highest value and used hardware flow control. Then I transmitted a very large file multiple times in both directions.

I have already looked at the Linux Test Project, but I didn't see anything that would fully exercise the ttyS0 port.

The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

Bill, I thought I had selected your solution as the "Accepted Solution", but for some reason Duncan got it? I didn't get the answer I was hoping for, but I appreciate both of your inputs.

Thanks

Anthony
