6.35 LAU_CONFIG_GETCOMSERMODE
(0x0110)
SCOM Serial Interface Mode
Returns the software configured serial interface mode. The value returned by this
functions is used, if the monitor is configured to override the DIL (DIP) switch
settings. The serial interface mode indicates the physical type of the serial interface
used for the SCOM communication. Available modes are RS232 and RS485. RS232
allows a point-to-point communication, i.e. computer and monitor or monitor and
monitor. With RS485, many monitors can be attached to the same physical line and
can be controlled by one or more computers, allowing a kind of networking. Limi-
tation is given only by the physical characteristics of the RS485 bus.
