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.
