Windows 10 & mscomm32.ocx run time error

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

 

Did someone have experiences in windows 10 with VB6 programs that read / write the serial port ?

 

Papergion, any luck with getting VB6 using the serial port under Windows 10? I have the same problem with VB6/Win10 and a PIC board emulating a serial port. Everything works fine under windows 7, but not under windows 10. From what I read after some Google'ing, it appears to be a problem in mscomm32.ocx, but I can't find any solution.
Simply reading from the port using "inpbuf = Mscomm1.Input" when characters are received, produces the error "run time error 8020: Error reading comm device"
