@NOYB:

So why do y'all have your serial port enabled if you are not using it.

Why would we turn it off unless we needed the resources (mostly IRQ) for another device or if it was a security risk?

Didn't your ma'ma ever teach you to turn off the lights when you leave a room vacant. Less is more.

I don't think you will save energy by turning it off especially considering that the chip involved do other things as well…

If it ain't being used put it away, put it into storage, throw it away, turn it off. Get the picture?

No, should we?

It's the same sort of philosophy as with security. Only what is needed is permitted, stored/kept, provided, etc.

I agree with you here but here there is actually a good and valid reason to do it…

First thing I did when initially setting up my pfSense machine was go into the BOIS and turn off everything not being used. Like the built in modem (yeah it's that old), printer port, etc.

Built-in modem? What is it, a PCJr? I have had plenty of PCs (and even non PCs like Apple II compatible and Sinclair ZX81) and I don't recall any of them ever had a built-in modem.

Less is more.

Some times we people are our own worst enemy.

If you did not have the number of posts you have here I would have hesitated between thinking this was flame bait or trolling…

I doubt this is the case considering your implication here but this is what it seemed to be at first glance...
