Since it appears from your dmesg that you disabled your motherboard's first serial port (usually
IRQ, 0x3f8), you can use the FreeBSD kernel configuration screen to make sio0 match your PCI
modem parameters.
To enter the kernel configuration screen:
* Press a key other than Enter when you see the "Hit [Enter] to boot immediately, or any other
key for command prompt." message during boot.
* At resulting prompt, enter 'boot -c' command.
* At next resulting prompt, enter 'visual' command.
* Top part of kernel config screen are enabled device drivers, bottom are disabled. You want
to go to the 'communications' section and change the parameters for sio0 (if you've truly
disabled it on the motherboard and don't need it) to match your PCI modem.
* Press Q to save the parameters and Q again to save the kernel configuration.
