Hello all.

I have a strange problem with handeling the com ports on my system.

I have written a program in VB2008 and I want to use this for sending out data through the serial ports in my system.

When i start the program it will identify the ports and it tells me that i have : Com1, Com2 and Com5 availeble. Com5 is a USB to serial adapter from ATEN.

Everything works just perfect with Com1 and Com2 and i have checked this for a long time, BUT then i try to send the same data to COM5 (USB to serial) it just sends (randomly) a couple of data and then suddenly crashes the system with a reboot.

It realy irritates me and i would like to understand why this happens.

Any suggestions??

Please.

Hi,

You may have a try connecting the USB to serial adapter to Com1 and perform a test on the Com1 to see if the problem still exists. You may perform test on another machine.

If the problem still exists, you can submita bug report on this issue in the Microsoft Connect web site:
