Device 
handling

Terminal I/O

 - The Terminal device is used for command and control of the

U4650. This I/O is a basic VT100-like emulation. All I/O is prompted by user-
input text strings terminated in carriage-returns. The terminal, whether local or
(via modem) remote, should be set to local echo ON. The unit only echoes a
carriage-return/linefeed and then a ‘>’ prompt after user entry. (But see 

Serial

Bus Control

 below.)

Serial Bus Control

 - If enabled by the factory, the Unity 4650 supports "daisy-

chaining" of terminal control. This involves sharing of a serial bus between
two or more IRDs. The serial bus consists of both the transmit and receive
serial port lines wired in parallel, connected to a serial port on all the IRDs and
the terminal communication device (either a local terminal or modem).

Certain volatile operating states are defined for IRDs using this daisy-chain
capability. These are Talker, Idle, and Waiting For Password. Units will transi-
tion from either Talker or Idle over to Waiting For Password when a wakeup
hotkey is received from the user. Then, after the two-digit ID passcode is
received, any unit matching that passcode proceeds to Talker (and switches its
serial output to active), while all others proceed to Idle. While in an Idle state,
a unit's serial port which is allocated as a Terminal and/or Modem device has
an electrically isolated (tri-state) output and responds only to a hotkey input.
When in the Talker state, the unit issues prompts and responds to commands
normally. Note that these states are held only in volatile memory and that a unit
reverts to the Idle state 

during

 and after a unit reset.

The unit ID is a non-volatile control assigned by the user. This daisy-chain
capability is effectively disabled by assigning a Unit ID of '00'. This leaves an
IRD continuously in the normal Talker state even through unit resets.

Modem I/O

 - The Modem device operates in a similar manner to the Terminal

device. Whereas the Terminal device was limited to a specific configuration,
the modem device may be set to one of several. The Modem device does not
use special handshaking or special control characters, and only supports auto-
answer modems. To access the modem command interface, the serial-port
device must first be set to Modem. The "Terminal/IO" discussion above on
emulation and echoing would then apply. The user would send the unit a car-
riage return and then the unit would return a prompt to enter the "modem pass-
word". If the correct password is entered, then modem access is enabled. Upon
enabling modem access, the U4650 will output a welcome banner.  After that,
I/O is indistinguishable from normal terminal access, with the same restriction
on local user access as set by the Network. Modem access is disabled when
either (1) a new input serial-port device is selected, (2) when there is no user
input for 10 minutes, (3) the OH command is received, or (4) the unit is reset.
