Technical information

Serial Solutions NewBIOS Reference
the card so that it can identify the source of any interrupt- port 1
is not assumed to be COM1 and so on.
The interrupt set via (or assumed by) NewBIOS service
0AFH is ignored by the device driver for Flynix-8 cards as the
interrupt specified here is used instead.
This service is used to set up each port on the card that
will use interrupt sharing (ports on the card can be switched
from the interrupt sharing hardware to a standard interrupt line).
Other Points.____________
NewBIOS will allow the setting of card types and
dependent information for ports whose address has not yet been
set, but their address remains zero and they cannot be used.
