In addition to setting the COM parameter, a communication card with
many hardware options may also require changing the jumpers on the
communication card.
Connection of a serial communication protocol to a specific serial port
The serial communication protocol (instance) settings include a setting parameter called
Serial port n (n = protocol instance number). Setting options for this parameter are
"COM1", "COM2" and so on. The desired serial port for the protocol instance is selected
through this parameter.
All link setting parameters are not found in the COMn settings. Additional
link setting parameters are found in the setting parameter list of the used
serial protocol, since some serial protocol standards allow changes in link
parameters, while other protocol standards do not.

Serial link diagnostics and monitoring

Serial communication diagnostics and monitoring is divided between the serial link driver
and the serial communication protocol. The lower level physical and protocol-
independent aspects of the UART-based serial communication are monitored in the serial
link driver. Diagnostic counters and monitoring values are found via the LHMI in
Monitoring/Communication/COMn (n= 1,2,...).
