15.1.6.2 IMMEDIATE MESSAGE MODE
Immediate message mode provides multiplexing of all
messages from all ports to the designated host module
automatically. Data is buffered until an end of message
terminating character is received or 256 bytes are
received. The messages are sent to the host device and
can be preceded by a port identification code
corresponding to the unit, module, and port number or
the device name of the peripheral port that sent the
message.
15.1.6.3 IMMEDIATE DATA MODE
Immediate data mode is similar to immediate message
mode described above. The primary difference is that
immediate data mode does not wait for a message
terminating character to send data to the designated
host module. Data is sent to the designated host
module automatically, as soon as it is received by any
port on the peripheral communications module.
15.1.6.4 COMMAND MODE
Command mode provides multiplexing of single
messages, all messages, or all buffered data from
specified ports on request from a host computer. When
a host computer sends a data command, the
V50/V73/V74/V75/V76/V86/V87 sends a single message,
all messages, or all buffered data from the requested
port(s) through the host module. This information can
be preceded by a port identification code corresponding
to the unit, module, and port or the device name of the
peripheral port that sent the message. Complete
messages and/or buffered data are sent to the
