My laptop, no surprise, has no connectors for serial ports.

The BIOS details, show:

COM1 in 3F8 with IRQ 4
COM2 in 2F8 with IRQ 3

The "system information" utility shows

COM1 in 3F8 -3FF with IRQ 4
COM4 with no address nor IRQ

MY questions:

Is all this a leftover that nobody care to eliminate?
What's the reason for such inconsistent info?
Which is true?
How to know the above? (How to test?)

If I open my laptop, could I identify a valid point where to take the signal for a serial port if I accept the risk to install a proper connector?

All this is quite puzzling for me. Help appreciated.

COM ports in laptops belong to the past .. and BIOS is like shining artifact of that past ..
Much easier than to try to find non-existing hardware inside your laptop is to get USB-to-RS232 converter ..
