What is default irq for com2 and com 4?
The default IRQ for COM2 is typically 3, while for COM4, it is usually 5. These IRQ settings allow the operating system to manage hardware interrupts for the respective serial ports. However, these values can sometimes vary based on the system configuration and settings in the BIOS. Always check your specific system documentation for accurate IRQ assignments.
