Hi Janne60,
Windows 7 Serial Port Communication In C++
- To Windows a serial port or a disk based file both are IO devices. So, in order to open an existing file ( serial port ) all we need to know the name of the device ( COM1) and pass the creation flags as OPENEXISTING. If a COM port is opened successfully, the API returns handle to the com port just like a handle to a file.
- The Microsoft MS-DOS and Windows environments refer to serial ports as COM ports: COM1, COM2.etc. Ports numbered greater than COM9 should be referred to using the. COM10 syntax. Additionally, you may want to look over COM (hardware interface) for another basic starting point. I/O addresses.
COM port should be listed in Device Manager under Ports (COM & LPT).
I am developing Delphi application on Delphi 2010 XE RAD Studio under Windows 7. My application talks on the serial port non-stop. I am using AsyncPro for Delphi 2010. Serial communication and everything else on the computer I develop with works great without any problem.
See if you can find them. If they're not listed in the Device Manager, you can try these suggestions to see what’s preventing the ports from getting displayed in device manager.
Method 1: Check for hidden devices.
a.Go to Start, type “hdwwiz.cpl” (without quotes) and press Enter. This opens Device Manager.Free universal obd ii software.
b.Click on View menu and select Show hidden devices. See if this helps in getting the ports to list.

Device manufacturers often release updates to their drivers to enhance performance or fix compatibility issues. To get the latest driver, visit the support section of your motherboard manufacturer’s website.
Method 3: It could also be possible that either the motherboard has no COM ports or they are disabled in the BIOS (basic input/output system). Check your motherboard specifications and enable them if they exist.
