This is a great product and solved our issue with the dreaded 8020 error. My question is will there be any chance of a 64-bit version? That would make life perfect :)

If you are developing in VB6 (Visual Studio 6) then anything you you build will be 32bit so couldn't use a 64bit OCX anyway.

But if you are developing with .Net then maybe take a look at Comm64.DLL

That's a proper Managed .Net component that uses the standard MSComm32 syntax. Also handles the threading so the expected "OnComm" events are raised on the application UI thread so your application doesn't need to worry about threading.

I'm developing with MS-Access. So the control works in MS-Access 32-bit - but not in MS-Access 64-bit.

That's a limitation in 64Bit MS Access. It simply refuses to load an 32bit OCX components. It's basically impossible to mix 32bit with 64bit.

Many of Microsoft's own components are disabled in 64bit Access/VBA. That's why the default install of MS Office is still 32bit. There's no real need to use 64bit office unless you're using HUGE excel spread sheets with BIG numbers. There's no benefit with MS Access.

Using Windows 11 (64 bits) and Office21 (64 bits) VBA7, it is possible to receive serial sentences on PORT COM by using the VB code available on github.com/Serialcomms/Serial-Ports-in-VBA-Simple-2022/blob/main/SERIAL_PORT_SIMPLE_VBA7.bas
I tested it successfully in late 2022. It is working very well. The only limitations is that you can only open one port COM at a time.
