![]() ![]() To avoid confusion over which port I am talking about, I will use COM1 on Windows and /dev/ttyS0 on Linux to map these names to the same IO ports and IRQs. The example I will be discussing involves both operating systems. ![]() Linux uses a format of /dev/ttyS0, /dev/ttyS1, and so on. On a Windows machine, the ports are named COM1, COM2, etcetera. Windows and Linux use very different naming conventions to identify serial ports. ![]() Thatâs the reason for this post, but before proceeding, letâs talk a little about serial ports. You can use serial port VirtualBox guide , but it also can be tricky. The only drawback is that there are multiple ways to accomplish this, which can be confusing.

My main operating system is Windows XP, but many projects I am involved in require me to use Linux.

Serial port access is critically important in my role as an embedded software engineer. ![]()
