If more numbers (1-8) are received before the
choose to route data to more than one of the multiplexed ports a the same
time. The first valid number between 1 and 8 sets the port that will be used of
receiving serial data and routing to the Br-SDC8ʼs ʻConfig./Mux. RS-232 portʼ
(female DE-09) or ʻMux./RS-422ʼ (female Rj-12) ports.
As an example, to send serial data out ports 3, 5, and 7, and listen to port 5
for any serial data which is returned, you would send the string: ʻAT+++537
2) ¼-J6 input bits 0, 1, 2 and 3: A binary pattern of bits presented on these four
