Serial Port Question

["Dana S. Wheeler" <dwheeler@gte.net>]

 My system doesn't recognize ttyS0 (which makes it difficult to
synch my Palm Pilot). I'm running Debian 2.2.r3 (Potato) on a Dell
Inspirion 7500 with a PCMCIA modem card on /dev/ttyS2.
I'm at a loss on what to do from here.
The information I've been able to gather so far is as follows:

bash-2.03$ setserial /dev/ttyS0
/dev/ttyS0, UART: unknown, Port: 0x03f8, IRQ: 4
bash-2.03$ setserial /dev/ttyS1
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3
blackie:/home/dwheeler# setserial /dev/ttyS2
/dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 3
blackie:/home/dwheeler# setserial /dev/ttyS3
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

blackie:/home/dwheeler# ls -l /dev/ttyS*
crw-rw-rw-    1 root     dialout    4,  64 Feb 24 15:03 /dev/ttyS0
crw-rw-rw-    1 root     dialout    4,  65 Nov 30  2000 /dev/ttyS1
crw-r--r--    1 root     dialout    4,  66 May 31 07:13 /dev/ttyS2
crw-rw----    1 root     dialout    4,  67 Nov 30  2000 /dev/ttyS3

blackie:/home/dwheeler# cat /etc/serial.conf|egrep -v '^#'
/dev/ttyS0 uart 16550A port 0x03f8 irq 4 baud_base 115200 spd_normal skip_test
/dev/ttyS1 uart 16550A port 0x02f8 irq 3 baud_base 115200 spd_normal skip_test pcmcia

blackie:/home/dwheeler# ls -l /dev/modem
lrwxrwxrwx    1 root     root           10 May 31 07:05 /dev/modem -> /dev/ttyS2
blackie:/home/dwheeler# 

Any help would be greatly appreciated.
