8.3.4.12 Get transm.err.counters (GET_TECB)
With this call, the counts of the error counters for B-slaves are being read out (see
chapter 9).
With every reading out of the counts, the error counters will be restarted.
The counts are being read out via the corresponding host interface and will be de-
leted with every read access. The counter´s value is limited to 254. 255 will cause
a counter overflow.
The counts could be independent of the counters, which are displayed in the dis-
play of the gateway.
