MSCOMM is an Active X control that allows you to send and receive data via a
PC's serial port. It comes with VB6 Enterprise and Professional. If you have
the Learning edition a MSCOMM clone is availed for download free of charge
at http://ourworld.compuserve.com/homepages/richard_grier/xmcomm.htm

        I have played around with WIN95IO.DLL which is also free. Info on using it
to control a parallel port is available at
http://www.aaroncake.net/electronics/vblpt.htm

I know there are many others, but these are the only ones I am familiar
with.

Hope this helps!

Subject: [OT]: Visual Basic and Port Control


I just finished a project where I needed to provide a Windows based
utility that would in-circuit program the EEProm in a non-PIC device. I
wrote the PC application using VB6 and an IO Active X control from JS
Payne (www.jspayne.com). The IO control gives you all sorts of
individual control of the serial and parallel port lines and is quite
well documented.

This was a fast turn project and there wasn't a great amount of time
for research. I'm curious what other solutions people have used to be
able to manipulate the individual lines on COM and Printer ports under
Windows?
