The Board Information window appears. This window shows the base address, IRQ
number, and number of ports for the selected modem card. To change one of these
options, select the field and type a new value.
Note: Setting the wrong base address and IRQ value can lead to unpredictable results.
Base Address
This is the base I/O address for the modem card in hexadecimal format. It provides
the RASExpress server with information about card activity, and allows the card to
use one interrupt for all ports on the card. Up to three modem cards can be used in a
RASExpress server. Each card must have a unique base I/O address number.
IRQ Number
This is the IRQ number for the modem card. The IRQ number used for each modem
card must be unique to the card. The IRQ requests the attention of RASExpress and
the computer’s microprocessor.
Number of Ports
This is the number of ports on the modem card.
Press E
SC to return to the ISI Card Setup window. To add a new card to this win-
dow, press I
NSERT and enter the base address, IRQ number, and number of ports in
the Board Information window.
To remove a modem card from the ISI Card Setup window, select the card and press
D
ELETE.
Line Information
To edit line information for an ISI card, select the card in the ISI Card Setup window
and press F2. The List of Lines window that appears lists the physical ports, or lines,
served by the RASExpress server. Select any line in the list and press
F2 to test it, or
E
NTER to configure it. The Line Information window that appears lists the parameters
that can be configured for the selected port. To edit a parameter, use the up and
down arrow keys to select the parameter, then press E
