What lines do you mean?  The [serialports] lines aren't normally
commented.  Do you mean the [ports] lines?  Did you put something in
those lines that made sense for your hardware, or did you just remove
the ; ?  The numbers that are there in the sample config do not touch
the serial ports on your average ix86 box.
(from man setserial)

       The "standard MS-DOS" port associations are given below:

              /dev/ttys0 (COM1), port 0x3f8, irq 4
              /dev/ttys1 (COM2), port 0x2f8, irq 3
              /dev/ttys2 (COM3), port 0x3e8, irq 4
              /dev/ttys3 (COM4), port 0x2e8, irq 3

And what do you mean by serial port access?  This letter comes by wine
through com3.  I haven't anything for [ports], just

[serialports]
"Com1" = "/dev/ttyS0"
"Com2" = "/dev/ttyS1"
"com4" = "/dev/ttyS3"

That's not direct port access, just access by the normal windows comm
API - CreateFileA, ReadFile, WriteFile, and so on.  Whether a user can
get at the comm ports this way is up to the linux system administrator.
If you can do it from the linux command line with minicom or cu -l, wine
can do it.

For direct port access, wine must be run by root, and I don't know how
well that works.

Everything comes from somewhere.  Everything has to go somewhere.
There ain't no such thing as a free IRQ.
