NAME

       ttymux - Serial I/O multiplexing STREAMS device driver

SYNOPSIS

       multiplexer@0,0:input

       multiplexer@0,0:output

DESCRIPTION

       ttymux is a STREAMS  multiplexer driver that connects multiple serial devices to the system console. Using this driver, input from multiple
       physical devices can be multiplexed onto a single input stream for the system console. Output written to the console can be distributed	to
       multiple  physical  devices  to provide redundant console interfaces to a system. Input and output can be multiplexed to or from a separate
       list of devices.

       ttymux is a STREAM's multiplexer for serial drivers (such as se(7D)) that comply with the Solaris terminal subsystem interface.

       Currently, multiplexer interfaces are provided for system console I/O only and not for general serial I/O multiplexing. Multiplexer  inter-
       faces are currently not available for all platforms. Please see NOTES.

NOTES

       Successful  loading  of	this  driver  and its services depends on the EEPROM or NVRAM settings in effect at the most recent system reboot.
       Without the platform firmware support, this feature cannot be enabled. Currently, this support is provided only on a NetraCT  product  fam-
       ily.

       Use  caution  when  enabling  this feature to perform console input multiplexing, particularly during super-user login. Because no security
       measures are enabled when the driver is in operation, you must clearly understand the security implications involved in using this  feature
       and  take  appropriate  measures  to  provide  maximum  protection to the host. This can include such steps as enabling input to physically
       secured console devices only.

       The ttymux driver does not handle the behavioral differences in control characteristics of different terminal types (for example, an ESCAPE
       sequence.) As a result, multiple terminal types are not supported simultaneously. Please refer to the platform user guide for more informa-
       tion.

NAME

       hid - Human interface device (HID) class driver

SYNOPSIS

       keyboard@unit-address
       mouse@unit-address
       input@unit-address:consumer_control

       The hid driver is a USBA (Solaris USB Architecture) compliant client driver that supports the Human Interface Device Class (HID) 1.0 speci-
       fication. The Human Interface Device (HID) class encompasses devices controlled by humans to operate computer systems. Typical examples	of
       HID  devices include keyboards, mice, trackballs, and joysticks. HID also covers front-panel controls such as knobs, switches, and buttons.
       A USB device with multiple interfaces may have one interface for audio and a HID interface to define the buttons that control the audio.

       The hid driver is general and primarily handles the USB functionality of the device and generic HID functionality. For example, HID  inter-
       faces  are  required to have an interrupt pipe for the device to send data packets, and the hid driver opens the pipe to the interrupt end-
       point and starts polling. The hid driver is also responsible for managing the device through the default control pipe. In addition to being
       a USB client driver, the hid driver is also a STREAMS driver so that modules may be pushed on top of it.

       The HID specification is flexible, and HID devices dynamically describe their packets and other parameters through a HID report descriptor.
       The HID parser is a misc module that parses the HID report descriptor and creates a database of	information  about  the  device.  The  hid
       driver  queries	the HID parser to find out the type and characteristics of the HID device. The HID specification predefines packet formats
       for the boot protocol keyboard and mouse.
