When data transfer begins, the COMM LED on the Dolphin HomeBase will blink red
and green. A unit remains selected until another unit in the network is selected. For
example, the string <ESC>HHPS3 would select the unit with ID number 3 for
communications. That unit would then send back an <ACK>3.
A selected unit in the Dolphin HomeBase network will assert the DSR signal of the
HomeBase when a Dolphin terminal is present. The DSR signal can be used by the
host application to determine if a Dolphin terminal is present and selected.
