Hi I too have been looking for a way to access the comm ports using managed code. I'm pretty new to Visual C++ so I need a little more information regarding how to setup and access a com port connected to a USB-Serial adapter. My comm port shows up as COM7 in windows. I need baby steps for opening, configuring and sending and receiving data. I only need to send about 5 or 6 chars but can possibly receive 10 or up to 512 chars from the serial device I'm interfacing with. All the code I've come across on the web doesn't seem to work with Visual C++ 2005 expess Edition.:confused:
