send the command $BTB2,3,4<cr> to the V71 host
module where <cr> is Carriage Return. The 4-port serial
module remains in broadcast mode until the V71 host
module issues a disconnect command consisting of the
port select code followed by Carriage Return (e.g.,
$BT<cr>).
If a peripheral communications module is configured to
operate in immediate reporting mode (see Section
15.2.2) and the destination V71 places that module into
broadcast mode, the destination V71 can receive data or
messages from the peripheral ports while
simultaneously broadcasting data out to the ports.
While in broadcast mode, other V71 host modules can
connect to the I/O module(s) and issue data commands
if the module(s) are in command reporting mode. The
clear buffer command can be issued to any 4-port serial
module in broadcast mode by another V71 host module
regardless of the programmed reporting mode.
15.2.6 DATA/MESSAGE PRESENTATION
Data presentation varies slightly in format depending on
the reporting mode you are using. In full duplex mode,
data is presented to the host computer and selected
peripheral exactly as it is transmitted and/or received
(i.e., the V50/V73/V74/V75/V76/V86/V87 module does
not add any extra characters).
In immediate reporting mode, messages are sent to the
designated host computer with an optional port
identification code preceding the actual message. For
example, suppose the 4-port serial module is installed
in Unit 1 as Module 2, Port ID is enabled, Line Feed (0A
Hex) is the programmed message terminate character,
and time tag is enabled. The 4-port serial module
sends complete messages to the designated host
