I am trying to get virtual serial boot console working with ilo
standard on a
proliant DL380G4.

Since the ILO reserves COM1, I need to redirect the console to COM2
and
reconfigure the boot parameters. The BSD handbook says to use this
line
in the kernel configuration file:

device sio1 at isa? port IO_COM2 flags 0x10 irq 3

but config reports a syntax error on this line. Is the handbook in
error? Do I need to set the flags for sio1 in the HINTS file? What is
the correct way to change the com port?

Thanks,
