Hi
I have some old programs, developed in VB6 that use the serial port with mscomm32.ocx
This programs works fine on windows XP, 7, 8, 8.1
After windows 10 installation this happens:
- Program start normally
- When i click a button, the program do this steps:
open the serial port (no errors)
try to read a serial character (no errors)
send a serial character (no errors)
try to read an answered serial character and receive the error:
"run time error 8020" "Error reading comm device"
- I have RE-registered mscomctl.ocx and mscomm32.ocx -> nothing change
- I have RE-installed usb/serial driver -> nothing change
The device work fine using a standard communication utility like "putty".
Any suggestion?
thanks
