FBSD 4.9 with GENERIC kernel found my PCI modem.
The PC's bio's has all com ports disabled.
The boot log shows this.

sio0: <Lucent kermit based PCI Modem> port
0xe400-0xe407,0xe000-0xe0ff,0xdc00-0xdcff mem 0xe2000000-0xe20000ff
irq 3 at device 19.0 on pci0
sio0: moving to sio4
sio4: type 16550A

This is an zoom modem model 2920. It has onboard DSP and controller.

What do I tell user ppp the modem's device is?

How can I send Hayes AT commands to modem?
