Hello All,

I've uploaded a new set of VBA functions for anyone still interested in using Serial COM Ports with Access.

Functions are generic for Excel, Access & Word , also cross-posted to Excel forums Serial COM Ports in Excel VBA - Microsoft Tech Community

Please let us know if they work for you thanks.
