Up to now we used the MS Communication Control MSCOMM32.OCX for communication

Since the Windows Update KB969898 (ActiveX Killbits) we have problems to
insert the MSCOMM. Following error message is coming up: "The subject is not

You must install VB 6.0 to be able to run this patch fix. This article

quite a few library files listed).

Good luck,
