Mode 3 Single message from all ports - Same as Mode 2,
except that a single message from all peripheral devices
is sent to the host device upon request.
Mode 4 All messages from selected port - Same as Mode 2,
but with specific port selection.
Mode 5 Single message from selected port - Same as Mode
3, but with specific port selection.
Mode 6 Time division multiplexing - Provides automatic
multiplexing of data from peripheral devices by
continuously scanning all ports to check for characters in
the receive buffers. If a receive buffer contains data, it
is transmitted through the host port in data blocks with
each data block preceded by a port identification code.
Transmission continues until the buffer is empty or until
a user-specified data block length has been transmitted.
In addition to the modes of operation, you may select the serial port
configuration (baud rate, word size, stop bits, parity and XON/XOFF),
the message terminate character, the data block length, and the
control character. These configuration changes are accomplished by
entering the menu-driven configuration mode. Changes are saved in
non-volatile memory. The H-Series models will translate between
peripheral devices of different configurations.
