Hello,
I am experiencing some strange problems while using a usb to serial
adapter vs. a real comm port. The problems started with getting a blue
screen at random times. Changing usb to serial drivers seemed to fix
that problem. Now I am experiencing a problem where sometimes I am
getting a crash while using the usb adapter but everything works
perfectly while using a natural comm port. Has anyone else experienced
this problem. ...

receive process. In order to fix this, I have to close the port and reopen
the port again.
Why?!! Is there any way to fix...
