IOADDRESS, IOBASEADDRESS specifies the base I/O address
of the EtherJet CardBus Adapter with 56K Modem I/O ports, in
hexadecimal notation. The EtherJet CardBus Adapter with 56K
Modem requires 128 contiguous I/O addresses if run in I/O mode.
If using memory-mapped I/O mode, no I/O ports are necessary. If
not used, the driver detects an I/O port automatically.
I/O PORT see IOADDRESS
IRQ specifies a hardware interrupt for the adapter. If PCI inter-
rupts are used on the CardBus bridge, this parameter is ignored
(unless the ISAIRQ keyword is used as an override). If this
parameter is not specified the driver detects an IRQ automati-
cally.
ISAIRQ use this keyword to force ISA IRQ routing. Some Card-
Bus bridges have the capability of supporting both PCI and ISA
style IRQ routing. The driver automatically determines the best
choice for this option unless this keyword is used as an override.
LATENCY specifies the latency timer for the CardBus Bridge.
This parameter affects the bus mastering capabilities of the
EtherJet CardBus Adapter with 56K Modem. Changing this
parameter may affect system performance. The range is a deci-
mal number between 1 and 255. The default is 32. The latency
should be lowered if more than one peripheral device, such as a
modem, is being used. If the EtherJet CardBus Adapter with 56K
Modem is the only peripheral being used, use a higher latency,
such as 255.
LINEMODE (For 16-bit DOS Drivers) selects either half-duplex
or full-duplex mode for the network. Valid parameters are AUTO,
HALF or FULL. Selecting full-duplex enables the EtherJet Card-
Bus Adapter with 56K Modem to send and receive data simulta-
neously when connected to a full-duplex hub. Default is AUTO.
LINEMODE (For 32-bit NDIS3 Driver IBMC.SYS) selects either
half-duplex or full-duplex mode for the network. Valid parameters
are AutoDetect, Half Duplex, and Full-Duplex. Selecting full-
duplex enables the EtherJet CardBus Adapter with 56K Modem
to send and receive data simultaneously when connected to a
full-duplex hub. Default is keyword is AutoDetect.
LINESPEED (For 16-bit DOS Drivers) forces operation to 10 or
100 Mbps. If the keyword is not present the line speed will be
automatically detected (default).
