Yes, has been for years.

ls -l /dev/modem
lrwxrwxrwx  1 root root 10 2006-07-18 20:29 /dev/modem -> /dev/tts/1

sudo /sbin/setserial /dev/ttyS1 -a

/dev/ttyS1, Line 1, UART: unknown, Port: 0x02f8, IRQ: 3
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal skip_test auto_irq

ttyS1 used to be the place from which to run the modem I know for sure when I 
had kppp installed.

 sudo /sbin/setserial /dev/ttyS2 -a

/dev/ttyS2, Line 2, UART: unknown, Port: 0x03e8, IRQ: 4
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal skip_test auto_irq

Now this is the output in Fed4 at ttyS0:

/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal skip_test

To which modem etc. connects properly.

Doing
sudo /sbin/setserial /dev/ttyS1 uart 16550A
I get
heisspf@~:$ sudo /sbin/setserial /dev/ttyS1 -a         
/dev/ttyS1, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal skip_test auto_irq

With microcom which I snatched from my DSL box where again the modem is 
working properly:
sudo  /usr/local/Microcom/microcom
Try /dev/ttyS0
/dev/ttyS0 not found
Try /dev/ttyS1
/dev/ttyS1 not responding (after I set the uart 16550A)

Try /dev/ttyS2
/dev/ttyS2 not responding

Try /dev/ttyS3
/dev/ttyS3 not responding

In this kernel 2.6.16 there is no more ttyS0 instead /dev/tts/1 to 3. I know 
it was working with kernel 2.6.14 but now it does not even work with 2.4.31.

Something broke somewhere.

Fedora4 does not run setserial neither does DSL.
