CONFIG_IRTTY_SIR
  Say Y here if you want to build support for the IrTTY line
  discipline.  If you want to compile it as a module (irtty.o), say M
  here and read <file:Documentation/modules.txt>.  IrTTY makes it
  possible to use Linux's own serial driver for all IrDA ports that
  are 16550 compatible.  Most IrDA chips are 16550 compatible so you
  should probably say Y to this option.  Using IrTTY will however
  limit the speed of the connection to 115200 bps (IrDA SIR mode).

  If unsure, say Y.

CONFIG_IRPORT_SIR
  Say Y here if you want to build support for the IrPORT IrDA device
  driver. If you want to compile it as a module (irport.o), say M here
  and read <file:Documentation/modules.txt>.  IrPORT can be used
  instead of IrTTY and sometimes this can be better.  One example is
  if your IrDA port does not have echo-canceling, which will work OK
  with IrPORT since this driver is working in half-duplex mode only.
  You don't need to use irattach with IrPORT, but you just insert it
  the same way as FIR drivers (insmod irport io=0x3e8 irq=11).  Notice
  that IrPORT is a SIR device driver which means that speed is limited
  to 115200 bps.

  If unsure, say Y.

CONFIG_USB_IRDA
  Say Y here if you want to build support for the USB IrDA FIR Dongle
  device driver.  If you want to compile it as a module (irda-usb.o),
  say M here and read <file:Documentation/modules.txt>.  IrDA-USB
  support the various IrDA USB dongles available and most of their
  pecularities.  Those dongles plug in the USB port of your computer,
  are plug and play, and support SIR and FIR (4Mbps) speeds.  On the
  other hand, those dongles tend to be less efficient than a FIR
  chipset.

  Please note that the driver is still experimental.  And of course,
  you will need both USB and IrDA support in your kernel...

CONFIG_WINBOND_FIR
  Say Y here if you want to build IrDA support for the Winbond
  W83977AF super-io chipset.  This driver should be used for the IrDA
  chipset in the Corel NetWinder.  The driver supports SIR, MIR and
  FIR (4Mbps) speeds.

  If you want to compile it as a module, say M here and read
  <file:Documentation/modules.txt>.  The module will be called
  w83977af_ir.o.

CONFIG_NSC_FIR
  Say Y here if you want to build support for the NSC PC87108 and
  PC87338 IrDA chipsets.  This driver supports SIR,
  MIR and FIR (4Mbps) speeds.

  If you want to compile it as a module, say M here and read
  <file:Documentation/modules.txt>.  The module will be called
  nsc-ircc.o.

CONFIG_TOSHIBA_FIR
  Say Y here if you want to build support for the Toshiba Type-O IR
  chipset.  This chipset is used by the Toshiba Libretto 100CT, and
  many more laptops.  If you want to compile it as a module, say M
  here and read <file:Documentation/modules.txt>.  The module will be
  called toshoboe.o.

CONFIG_SMC_IRCC_FIR
  Say Y here if you want to build support for the SMC Infrared
  Communications Controller.  It is used in the Fujitsu Lifebook 635t
  and Sony PCG-505TX.  If you want to compile it as a module, say M
  here and read <file:Documentation/modules.txt>.  The module will be
  called smc-ircc.o.

CONFIG_ALI_FIR
  Say Y here if you want to build support for the ALi M5123 FIR
  Controller.  The ALi M5123 FIR Controller is embedded in ALi M1543C,
  M1535, M1535D, M1535+, M1535D Sourth Bridge.  This driver supports
  SIR, MIR and FIR (4Mbps) speeds.

  If you want to compile it as a module, say M here and read
  <file:Documentation/modules.txt>.  The module will be called
  ali-ircc.o.

CONFIG_VLSI_FIR
  Say Y here if you want to build support for the VLSI 82C147
  PCI-IrDA Controller. This controller is used by the HP OmniBook 800
  and 5500 notebooks. The driver provides support for SIR, MIR and
  FIR (4Mbps) speeds.

  If you want to compile it as a module, say M here and read
  <file:Documentation/modules.txt>. The module will be called vlsi_ir.o.

CONFIG_DONGLE
  Say Y here if you have an infrared device that connects to your
  computer's serial port. These devices are called dongles. Then say Y
  or M to the driver for your particular dongle below.

  Note that the answer to this question won't directly affect the
  kernel: saying N will just cause the configurator to skip all
  the questions about serial dongles.

CONFIG_ESI_DONGLE
  Say Y here if you want to build support for the Extended Systems
  JetEye PC dongle.  If you want to compile it as a module, say M here
  and read <file:Documentation/modules.txt>.  The ESI dongle attaches
  to the normal 9-pin serial port connector, and can currently only be
  used by IrTTY.  To activate support for ESI dongles you will have to
  start irattach like this: "irattach -d esi".

CONFIG_ACTISYS_DONGLE
  Say Y here if you want to build support for the ACTiSYS IR-220L and
  IR220L+ dongles.  If you want to compile it as a module, say M here
  and read <file:Documentation/modules.txt>.  The ACTiSYS dongles
  attaches to the normal 9-pin serial port connector, and can
  currently only be used by IrTTY.  To activate support for ACTiSYS
  dongles you will have to start irattach like this:
  "irattach -d actisys" or "irattach -d actisys+".

CONFIG_TEKRAM_DONGLE
  Say Y here if you want to build support for the Tekram IrMate 210B
  dongle.  If you want to compile it as a module, say M here and read
  <file:Documentation/modules.txt>.  The Tekram dongle attaches to the
  normal 9-pin serial port connector, and can currently only be used
  by IrTTY.  To activate support for Tekram dongles you will have to
  start irattach like this: "irattach -d tekram".

CONFIG_GIRBIL_DONGLE
  Say Y here if you want to build support for the Greenwich GIrBIL
  dongle.  If you want to compile it as a module, say M here and read
  <file:Documentation/modules.txt>.  The Greenwich dongle attaches to
  the normal 9-pin serial port connector, and can currently only be
  used by IrTTY.  To activate support for Greenwich dongles you will
  have to insert "irattach -d girbil" in the /etc/irda/drivers script.

CONFIG_LITELINK_DONGLE
  Say Y here if you want to build support for the Parallax Litelink
  dongle.  If you want to compile it as a module, say M here and read
  <file:Documentation/modules.txt>.  The Parallax dongle attaches to
  the normal 9-pin serial port connector, and can currently only be
  used by IrTTY.  To activate support for Parallax dongles you will
  have to start irattach like this "irattach -d litelink".

CONFIG_OLD_BELKIN_DONGLE
  Say Y here if you want to build support for the Adaptec Airport 1000
  and 2000 dongles.  If you want to compile it as a module, say M here
  and read <file:Documentation/modules.txt>.  The module will be
  called old_belkin.o.  Some information is contained in the comments
  at the top of <file:drivers/net/irda/old_belkin.c>.
