followed by a message from Module 2 Port 2 followed by
a message from Module 3 Port 2, and so on.
NOTE: The designated host computer can select and
transmit data to any serial port while simultaneously
receiving messages from all ports. A terminal connected
to a non-designated host module can select and send
data to any port. However, messages are sent to the
designated host terminal only. If a connection exists
between a host module and the desired port, the
requesting host module is sent a busy message.
If a designated V71 is currently receiving messages and
the host computer selects a port on a
V50/V73/V74/V75/V76/V86/V87 operating in immediate
or command mode, the messages continue to be sent to
the host computer. If the host computer selects a port
on a module operating in full duplex mode while
receiving messages, the messages stop until the host
computer disconnects. If the host computer selects a
module operating in command mode while receiving
messages, messages continue to be sent until the host
issues a data command (not CBn<cr>). The messages
do not resume until the host disconnects from the
module.
The V71 host module can make a full duplex connection
to a serial port when the peripheral module is operating
in full duplex, immediate message, or immediate data
mode by sending the port select code, the peripheral
module number, a comma, the peripheral port number,
Capital "F", and Carriage Return or Line Feed.
For example, if the default port select code is used
($BT) and the peripheral module is installed as Module
2, peripheral port 1 is selected for full duplex
communication by sending $BT2,F<cr> or $BT2,1F<lf>
where <cr> is Carriage Return and <lf> is Line Feed.
