serial link driver. Diagnostic counters and monitoring values are found via the LHMI
in Monitoring/Communication/COMn (n= 1,2,...).
Depending on the communication protocol, the serial driver software receives single
characters or complete protocol frames, based on the frame start/stop characters or
on timing.
Monitoring data for a COM channel can be divided into basic and detailed diagnostic
counters.
