When the parameter has been set, a power down or software reset
(using EX) must be performed for the complete system. Not doing
so may result in undefined behaviour.

Type Communication command
Syntax SETCOM(baud_rate, data_bits, stop_bits, parity, port_number, mode)
Description The SETCOM command sets the serial communications for the serial ports.
The command will enable the Host Link protocols or define the general-pur-

default settings are recovered at start-up.
