VB Help

[ScaleRobotics]

You could use the timer, but the best way would be to use a comm port event. That way you are only doing something when data arrives. Its been years (and years) since I wrote a VB program with serial port, so I am sure others can do better than my try at answering this. But here is something I found for a newer version of VB.

http://www.me.umn.edu/courses/me2011...al-port-vb.pdf Toward the end, it mentions why things get a little complicated: "For receiving data at unexpected times, use the DataReceived event. This is a bit tricky
because it runs in a different thread and requires a handler. (Virtual Serial Port Cookbook,
Chapter 9 for details.)" Of course it is in chapter 9. Chapters 1 - 6 are free: http://www.smileymicros.com/index.ph...age&PAGE_id=50
