Syntax
SETCOM(baud_rate, data_bits, stop_bits, parity, port_number, mode)
Description
The

command sets the serial communications for the serial ports.
The command will enable the Host Link protocols or define the general-pur-
pose communication.
The serial ports have 9,600 baud, 7 data bits, 2 stop bits, even parity and
