Modem not detected in FreeBSD 5.3

[hamsadhvani at netzero.net]

I have some problems getting my modem to work on FreeBSD 5.3.It is an internal modem 
Intel 537EP V9x DF PCI Modem sitting on COM3.  Originally the dmesg for the serial ports read: 
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
sio0: type 16550A
sio1: configured irq 3 not in the bitmap of probed irqs 0
sio1: port may not be enabled.
 My /boot/device.hints file reads as follows: 
hint.sio.0.at=isa
hint.sio.0.port="0x3F8"
hint.sio.0.flags="0x10"
hint.sio.0.irq="4"
hint.sio.1.at=isa
hint.sio.1.disabled="1"
hint.sio.1.port="0x2F8"
hint.sio.1.irq="3"
hint.sio.2.at=isa
hint.sio.2.disabled="1"
hint.sio.2.port="0x3E8"
hint.sio.2.irq="5"
hint.sio.3.at=isa
hint.sio.3.disabled="1"
hint.sio.3.port="0x2E8"
hint.sio.3.irq="9"

which I modified by commenting the disabled line and adding the 
following lines.
hint.sio.1.flag="0x0"
hint.sio.2.flag="0x201" (refered the sio4 manual but I am not sure if these are correct)
and then rebuilt and installed the kernel.

Still my dmesg read:
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
sio0: type 16550A
sio1: configured irq 3 not in the bitmap of probed irqs 0
sio1: port may not be enabled.
sio2: configured irq 5 not in the bitmap of probed irqs 0
sio2: port may not be enabled.
            
Thanks.
