Write and read settings not working.

[woko1754]

When sending Commands
"94 - Write Settings to EEPROM"
or
"95 - Read Settings from EEPROM"
to module 2x7A, I get no answer.
even after two retries. Here the trace of a version request followed by three read settings:

I's the same with write settings.

By sniffing the kommunikation I found out that at least the CRC-sum has to be added, like it was the case with the reset-command. The write command needs four bytes more, what ever they are.

I made it !
I had to add the CRC and in case of write settings adding a four byte magic number.
