V74/V75/V87 OPERATING IN THE DIFFERENT MODES
A typical application using a V74/V75/V87 module would have a host computer such
as an IBM PC connected to the host module and various devices such as cash
registers, digital laboratory instruments, bar code readers, numerical machines,
printers, modems, terminals, etc. connected to the serial ports.
Regardless of the mode of operation, any terminal connected to a host module can
connect and send data to a specific port by sending the appropriate port select
sequence followed by the data. A port select sequence consists of the port select code
(default is $BT), the desired unit number followed by a colon (1: to 30: - only if using
cascaded units), the desired module number (2 to 16), a comma, the desired port
number (1 to 4), and a terminating character (0A Hex - Carriage Return). The port
select sequence is not passed through to the selected port.
NOTE: When the host computer/controller selects an EIA-485 port on a
V87 module, all characters sent to the peripheral device are echoed back to
the host device.
Full duplex reporting mode provides bidirectional communication between the host
computer and the selected peripheral device. Data received by non-selected
peripheral ports is buffered until selected by the host computer.
Immediate message mode provides automatic message multiplexing. A message
begins when a port on the module receives a character from the device connected to
it. A message is completed when the message terminating character is received or
2048 characters have been received without a terminating character.
Immediate data mode is similar to immediate message mode. 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
