Recommendation for serial communications in Access 2007

I need to communicate with a bar code scanner connected over a serial port in Microsoft Access. In older versions of Access I was able to use a wrapper around MSCOMM32.ocx that no longer seems to work. I can't use wedge communication because I need to use ACK开发者_StackOverflow/NACK which is only supported through the RS232 interface and I need to send messages to the scanner, which is also only supported through the RS232 interface.

Are there any controls in widespread use that support serial communication in Access 2007?

EDIT: In case anyone comes across this, the newest version of MSCOMM32.ocx (I believe dated 3/09) still works fine as of this writing. It is older versions of MSCOMM32.ocx that do not work.

I can't vouch for the answer, but I can say that Tony Toews is a reliable person, and on this topic, he posted on his blog last year:

An older version of MSCOMM32.OCX has had the "kill bit" flag set.

As Tony says, it's almost always better to rely on Windows APIs than it is to build your app with connections to an ActiveX control. Windows APIs don't really have the versioning problems that ActiveX controls and OCX's do.
