In Appendix 6.1, you will find an overview of all mailbox commands sorted
according to groups and opcodes (see Appendix 6.1.1) or alphabetically ac-
cording to the names of the commands (see Appendix 6.1.2).
A detailed description of each command can be found in the reference to Ap-
pendix 6.3.
If a mailbox command is executed, the command is confirmed. The return
value is transmitted in byte 3 of the process data. Section 2.1.1.8.1.1 summa-
rizes the possible return values.
