Probably the easiest way to do this is to use the MSComm control.  It comes
with Visual Basic 4, 5,& 6.  With it you can write to or read the comm port
easily and the control works well with A95 or 97.   There are other controls
out there too.   If you want to do it all with code, then find a copy of
Roger Jennings book Access 2 Developer's Guide.  All the code you need for
comm control is in there.  You might have to hunt for the book at your local
store I'm not sure its still in print, but try Amazon etc. too.

I am not sure about the 16 bits version, but you may try MSCOMM.OCX (coming
with VB), just be carefull with the version in order to support 16 bits.
Interesting, those activeX control allow you to program "on event", rather
that polling the port continuously.

Another alternative, is to run an old DOS program and you communicate to it
through files (?) if this is possible (and acceptable for the use you make
of it).

Hope it may help,
