Hi All,
I have written a comms program using C# and modded it for a new board the company I work for has produced I did notice an oddity (the incoming message light flashed on the board) I then ran AGG soft's Advanced Serial Port Monitor and found the character 16C was being sent when the port was closed and to top it all my PC did a proper power off reset which was logged in Event Viewer as a System Error. I am wondering if this could be due to the board or the comm port on my (elderly) PC. I dont think its the comm software as I have used this program I wrote with multiple PC in multiple envoirments. Has anyone ever experienced something similar using AGG Advance Serial Port Monitor 3.85 Build 25??

Mmmm, just had another power/crash it appears as though if you open ASP in spy mode without any other code running it gives the following

I have no experience with that monitor, so no suggestions.
