NAME

       ifport - select the transceiver type for a network interface

SYNOPSIS

       ifport interface [auto|10baseT|10base2|aui|100baseT|##]

DESCRIPTION

       Ifport  sets  the  transceiver type for the specified network interface, for drivers that support multiple transceiver types.  If a type is
       not specified on the command line, then the current type is displayed.  The type can be specified either numerically or	by  keyword.   The
       five  standard  transceiver  types (auto, 10baseT, 10base2, aui, and 100baseT) correspond to codes 0 to 3, for all the Linux PCMCIA network
       drivers.  The keyword match is case insensitive.

       The network drivers may not reconfigure a card for a new transceiver type if the interface is already open.  It is best	to  invoke  ifport
       prior to configuring the interface with ifconfig to ensure that the new setting takes effect immediately.

       This  utility  only  works  with  a  limited set of 16-bit PC Card drivers: 3c589_cs, nmclan_cs, pcnet_cs, smc91c92_cs, and xirc2ps_cs.	If
       invoked for other drivers, ifport may report bogus transceiver settings, or report ``Operation not supported''.

DIAGNOSTICS

       ioctl: Operation not supported
	      Indicates that this network device does not support manual transceiver selection.  There may be only one transceiver option, or  the
	      device may always autodetect the appropriate transceiver.

NAME

       3c589_cs - 3Com 3c589 Etherlink III device driver

SYNOPSIS

       insmod 3c589_cs.o [pc_debug=n] [if_port=n] [irq_list=i,j,...]

DESCRIPTION

       3c589_cs  is  the  low-level  Card  Services driver for the 3Com 3c589 PCMCIA ethernet adapter and 3Com 3c562/3c563 combo cards.  When this
       driver is attached to a card, it allocates the next available ethernet device (eth0..eth#).  This device name will be reported in the  ker-
       nel log file, and passed on to cardmgr(8).

       With  the default transceiver setting, the driver will attempt to continuously autodetect the transceiver type (10base2 or 10baseT).  There
       should normally only be a one or two second lag before the correct transceiver is selected.  On particularly noisy or busy networks, it	is
       possible  for the detection logic to incorrectly toggle the transceiver type.  If this becomes a problem, it may be necessary to explicitly
       select the interface type when the module is loaded or with the ifport command.

PARAMETERS

       pc_debug=n
	      Selects the PCMCIA debugging level.  This parameter is only available if the module is compiled with debugging enabled.  A  non-zero
	      value enables debugging.

       if_port=n
	      Selects  the  transceiver type.  0 is autodetect (10baseT or 10base2), 1 is 10baseT (twisted pair), 2 is 10base2 (BNC, or thin net).
	      and 3 is AUI (thick ethernet).  The default is 0 (autodetect).

       irq_list=i,j,...
	      Specifies the set of interrupts that may be allocated by this driver.

DIAGNOSTICS

       eth#: interrupt(s) dropped!
	      Indicates that the driver did not receive an interrupt notification for some reason.  The driver will poll the card (with a signifi-
	      cant  performance penalty) if the problem persists.  The most likely cause is an interrupt conflict and/or host bridge configuration
	      problem.
