CAN I REMOVE SERIAL PORTS ? 1

Unlikely you will be able to remove them. But you should be able to disable them in your BIOS. Or with your setup disk if your computer is one of those.
Probably best to remove them with device mangler first , then cripple the CMOS entry on the next boot up. Ed Fair

Any advice I give is my best judgement based on my interpretation of the facts you supply.
Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

Boot to safe mode, remove them from device manager, restart, go into BIOS setup, disable them there, and you'll never see them again. Cheers,

Hey there, isn't COM3 logically cascaded to COM1 which both
inturn are connected to Physical serial port A (port 1) ?
So, if I do recall this to be so, then removing / disabling
Physical serial port A (port 1) you'll lose not only COM1
but, you'll lose COM3 too.

Any PnP device that needs a com port (modems) will assign themselves the next available port, AFTER any other device.
If the motherboard has both ports active, then com 3 will be taken by the modem (usually) and a separate IRQ assigned. This is normal PnP stuff.
If you DISable the onboard ports (com 1 and 2 (A and B)) they are then "free" for devices to use.
USR modems do like to use com 5 (even though there isn't supposed to be such a thing), but that's the nature of PnP.
Com 3 isn't necessarily "cascaded" from com 1, but they CAN share an IRQ (causing modems to give the error "Port Already Open"
.
Regardless of operating system, setting the BIOS "PnP Os Installed" to NO, can force peripherals to separate themselves better.
Things MUST be removed from device manager (in safe mode), before changing BIOS, fo that Windows can sort out it's resources better. Cheers,
